the difference between the two complementary angles are 180 degree find the measure of the angle answer |
|
Answer» = 135 and angle y = -45Step-by-step EXPLANATION:Let the angle (1) = xAnd, the angle (2) = yNow, A.T.Q.x + y = 90° -----------------equation(1)Also, x - y = 180° (given) ------------------equation(2)From (1) We GET, x = 90 - y ---------------equation(3)Putting equation (3) in (2)We get, (90 - y) - y = 18090 - y - y = 180-2y = 180 - 90-2y = 90So, y = -45This implies, x = 90 - (-45)So, x = 135Hence, angle x = 135 and angle y = -45Hope it helps you.please mark me as the brainliest. |

Help meh im so stuck |
| Answer» 2 rectangle's with perimeter 12 unitsSee, Perimeter of rectangle = 2(l+b) = 12l+b = 6 So, just take length and breadth one by one,LIKE when l = 1 then b = 5 When l = 4 then b = 2But remember you can't take l = b = 3 Because if you take this value then it becomes square.Similarly, For AREA of rectangle = l x b = 12When l = 1 then b = 12When I = 4 then b = 3When I = 6 then b = 2 That's it.There are 2 rectangle's with perimeter 12 and 3 rectangle's with area 12.Thanks! | |

Verify associative property of multiplication and addition for a=5 by 2, b=12 by 5, c=7 by 12 |
|
Answer» Step-by-step explanation:associative property :(i) for addition :a+(b+C)=5/2+(12/5+7/12)=5/2+(144/60+35/60)=5/2+(179/60)=150/60+179/60=329/60=5 and 39/60b+(a+c)= 12/5+(5/2+7/12)=144/60+(150/60+35/60)=144/60+185/60=329/60= 5 and 39/60 so ,associative property WORKS for addition.(ii)for multiplication:a*(b*c)=5/2*(12/5*7/12)=150/60*(144/60*35/60)=150/60*7/5=150/60*84/60=7/2=3 and 1/2 lets TRY another WAY,b*(a*c)=12/5*(5/2*7/12)=12/5*(30/12*7/12)=12/5*35/24=288/120*175/120=3 and 1/2 so, associative property is TRUE for multiplication.hope this helped . |

Is it possible to have a regular polygon if each interor angle is 110 |
|
Answer» In a regular polygon with n SIDES, the n central ANGLES each equal 360/n.The sides of the n-gon form the bases of triangles where the LEGS are radii.The base angles are then (180 - 360/n)/2 = 110This WOULD make n = 9/10 |
