Answer:
4x + 16
Step-by-step explanation:
Area of a triangle is:
A = ½ bh
Here, b = x+4 and h = 8:
A = ½ (x + 4) (8)
A = 4x + 16
26.6
Tan(26.6) = 0.5
8/16 = 0.5
Answer: x^2 + 19
Step-by-step explanation: Cancel out x^2 and add 7 and 12 together. 7 + 12 = 19. Next plug in x^2. So, its now x^2 + 19.
Hope this help!
