find the value of x
I will see that 6x will equivalent to 90° because both angle add together to get 180° and each of them has 90° each which is complementary angel, so here is the equation: 6x=90° Divided 6 to each side 6x/6=90°/6 x=15°, so your answer is B To prove this answer is correct, I will use another method to solve this. 6x and 90° both add together to get 180° for these two angels form the straight line called supplementary angels, so: 6x+90°=180° Subtract 90° to each side 6x+90°-90°=180°-90° 6x=90° Divided 6 to each side 6x/6=90°/6 x=15°. As a result, 15 is your final answer. Hope it help!
