Answer:
x = 10.3 in
Step-by-step explanation:
To find the value of a, use the area formula for a triangle. The formula is A = 1/2 *b*h. Here b = x and h= x. The formula becomes A = 1/2 *x². Substitute A = 53 and solve for x by using inverse operations.
A = 1/2x²
53 = 1/2x²
106 = x²
√106 = x
10.3 = x
Answer:
64.1°
Step-by-step explanation:
tan x = opp/adj
tan x = 20/9.7
tan x = 2.0619
x = tan^-1 2.0619
x = 64.1°
11/3. This is because you multiply the denominator by the mixed number. Than you add the numerator to that. Put that number over the denominator you had in the original problem. Hope this helps!
