The answer is (x+4) lmk if you want the steps.
Answer:
It would be 28 degrees.
Step-by-step explanation:
To find the angle, we simply need to pick two sides. We'll use the opposite side (24) and the adjacent side (45). Using these two, we can find the answer with the Tan function.
Tanα = Opp/Adj
Tanα = 24/45
Tanα = .53333
Tan-1α = .53333
α = 28 degrees
2x + 1.5x +20 = 90
3.5 x = 90-20
3.5 x = 70
x = 70/3.5
x = 20
angle DAE = 2*20 = 40
angle CAD = 1.5*20 +20 = 50
Answer:
-16b+40b^2
Step-by-step explanation:
-8b*2=-16b
(-8b)(-5b)=40b^2
