If angle B and angle Q are acute angles such that sin B=sin Q,then prove that angle B=angle Q |
| Answer» Let there be two triangles ABC and PQR such that angle C=90⁰ and angle R=90⁰now, sinB = AC/AB and SinQ=PR/PQsince, sinB = SinQ ⇒ AC/AB = PR/PQ⇒ AC/PR = AB/PQ and also angleC = angleR⇒ by SAS similarity, ∆ABC is similar to ∆PQRsince corresponding angles of similar triangle are equal ⇒ angleB = angleQ | |

quadrilateral equation |
| Answer» A\xa0quadratic equation\xa0is an\xa0equation\xa0of the second degree, meaning it contains at least one term that is squared. The standard form is ax² + bx + c = 0 with a, b, and c being constants, or numerical coefficients, and x is an unknown variable.\xa0The Babylonians came up with a technique called “completing the square” to solve common problems with areas by 400 BC. The first purely mathematical try to come up with a\xa0quadratic formula\xa0was done by Pythagoras in 500 BC. Euclid did the same thing in Alexandria, Egypt. Euclid used a purely geometric method. | |
