Can someone explain how to solve this
i have a quiz on this tmr

b₁ =

Step-by-step explanation:

Given

A = h(b₁ + b₂) ( multiply both sides by 2 to clear the fraction )

2A = h(b₁ + b₂) ← distribute

2A = hb₁ + hb₂ ( subtract hb₂ from both sides )

2A - hb₂ = hb₁ ( isolate b₁ by dividing both sides by h )

= b₁

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
