Answer:
sum of interior angle of a triangle is 180 degree
so,
3x +7 + 2x+7 +3x+6 = 180
8x + 20 = 180
8x = 180 - 20
8x = 160
x = 160/ 8
x = 20

Answer:
x=-26 2/3
Step-by-step explanation:
Make sure you have a negative in front of the mixed fraction.
Answer:
= 2sinA.cosA+ sinA / 1+cos2A+ cosA
= sinA(2cosA + 1) / 2cos^2A + cosA
= sinA(2cosA + 1) / cosA( 2cosA + 1)
= sinA / cosA
= tan A
= R.H.S
