Find the measure of each angle of a parallelogram if the larger angle of a parallelogram is 30° less than twice the smaller angle |
Answer» GIVEN :
To Find :
Solution :Sun of two adjacent angles of a parallelogram is equal to 180° LET the smaller angle be x Let the larger angle be 2x - 30° According to the QUESTION : ⟶ x + 2x - 30° = 180° ⟶ 3X - 30 = 180° ⟶ 3x = 180° + 30° ⟶ 3x = 210 ⟶ x = 210/3 ⟶ x = 70 Therefore :Smaller angle = x = 70° Larger angle = 2x - 30° = 2(70) - 30 = 140 - 30 = 110° So, all the angles of the parallelogram are 70° , 110° , 70° and 110° ━━━━━━━━━━━━━━━━━━━━━ |

X2+2x+3=0 find the two roots |
|
Answer» Answer: x = -1+2^0.5i and -1-2^0.5i Step-by-step explanation: We will use the quadratic formula for ax^2+ bx+c, where a= 1, b=2 and c=3. The discriminant D = b^2-4ac = -8, which is negative. Hence the SOLUTION will be two COMPLEX number. x=(-2 +- (D)^0.5)/2 = (-2 +- 2*2^0.5i)/2 = -1+2^0.5i and -1-2^0.5i, where i is the IOTA which is equal to (-1)^0.5 |

What should be added to the sum of 3pq + 5p²q² + p³ and p³ - pq to get 3p³ - 2p³ q³ + 4 pq? |
|
Answer» There are two possibilities Step-by-step explanation: I think the question is to get 3p³ - 2p²q² * + 4 pq not 3p³ - 2p³ q³ + 4 pq . Or the question should be LIKE What should be added to the sum of 3pq + 5p³ q³ + p³ *(instead of 3pq + 5p²q² + p³) and and p³ - pq to get 3p³ - 2p³ q³ + 4 pq? So let me ADD the answer of both the possibilities If the question is What should be added to the sum of 3pq + 5p²q² + p³ and p³ - pq to get 3p³ - 2p²q² + 4 pq? Then the answer should be p³ + 2pq -7p²q² Step by step explanation 3pq + 5p²q² + p³ +p³ - pq = 2p³ + 2pq + 5p²q² Let X be the number added to get 3p³ - 2p³ q³ + 4 pq. 2p³ + 2pq + 5p²q² + x = 3p³ - 2p²q² + 4 pq. x = p³ + 2pq -7p²q² Thus, To get 3p³ - 2p²q² + 4 pq, 2p³ + 2pq + 5p²q² must be added to p³ + 2pq -7p²q² If the question is What should be added to the sum of 3pq + 5p³ q³ + p³ and p³ - pq to get 3p³ - 2p³ q³ + 4 pq? Then the answer will be 3pq + 5p³ q³ + p³ + p³ - pq = 2p³ + 2pq + 5p³ q³ Let x be the number added to get 3p³ - 2p³ q³ + 4 pq 2p³ + 2pq + 5p³ q³ +x = 3p³ - 2p³ q³ + 4 pq x = p³ + 2 pq - 7 p³ q³ |

3.Show how root 5 can be represent in the number line |
|
Answer» Answer: Hint: We denote the points REPRESENTING 0 and 2 in the number line as O and A. We construct a right angled triangle OAB such that ∠OAB is the right angle and AB=1 unit. We USE the Pythagoras theorem and find OB=5–√ units. We take an ARC OB from the point of O and cut the number line at the point G. G represents 5–√ in the number line. Complete step-by-step answer: We know from Pythagora's theorem states that “In a right-angled triangle the square of hypotenuse is sum of squares of other two sides.” If h is the length of hypotenuse and p,b are the lengths of other two sides, then we have h2=p2+b2 If we can find a length of 5–√ and take an arc of that length from point 0 in the number line we can show the POSITION of 5–√. Let us choose the hypotenuse as h=5–√. So we haveh2=(5–√)2=5. We can choose two perfect squares p2=4,b2=1 such thatp2+b2=h2=5. Then we have p=2,b=1. We denote the point representing 0 and 2 in the number line as O and A. The line segment OA will be our choice for p=2.We draw the right angle at the point of A and construct the right angle triangle ΔOAB such that AB=1unit. The line segment OB will be our choice for p=1.
We see that in the above right angled triangle OAB is the hypotenuse h=OB. So by Pythagoras theorem we have, OB2=OA2+AB2⇒h2=p2+b2⇒h=p2+b2−−−−−−√⇒h=22+12−−−−−−√=5–√ We take the arc OB=5–√ from O and cut the number line at the point G. G will represent the number 5–√ in the number line.
Note: We note that 5–√ is an irrational number which means 5–√ cannot be expressed in the form of pqwhere p is any integer and q is a non-zero integer. We can alternative solve by choosing p2=2,b2=3 but or that we need to construct right angled triangles with hypotenuse of length 2–√,3–√units. 69.3K+ Views |
