Answer:
a = 7, b =
Step-by-step explanation:
Using the sine ratio in the left right triangle and the exact value
sin45° = , then
sin45° = = = ( cross- multiply )
a × = 7 ( divide both sides by )
a = 7
--------------------------------------------------------
Using the tangent ratio in the right triangle on the right and the exact value
tan60° = , then
tan60° = = = = ( multiply both sides by b )
b × = 7 ( divide both sides by )
b = × =
8x + 16 =6x
16 = 6x-8x
16 = -2x
X=-8
12% bc the difference is 21 and do 21 divided by 175 trust me
