Answer:
92
Step-by-step explanation:
angle a and b add up to 180 degrees
4x-20+2x+8=180
add like terms
6x+12=180
x=28
then substitute to get 92
Answer: 8
Step-by-step explanation: It's just GCF. The greatest common factor (GCF) of 8 and 16 is 8 (8 and 16 are both divisible by 8 but not by anything greater) which brings us to our answer.
Answer:
h = 32.2 ft
Step-by-step explanation:
Since we have a right triangle, to get the value of h, we will have to use the appropriate trigonometric ratio
From the diagram given, h faces the angle and that makes it the opposite side
62.5 ft faces the right angle and that makes it the hypotenuse
The trigonometric ratio that connects the two is the sine
thus, we have it that;
sine 31 = h/62.5
h = 62.5 * sin 31
h = 32.2 ft
12 units
(because 0,5 x 12 x 8 = 48)
