Answer:
see below
Step-by-step explanation:
(w+14)/2 = 10
Multiply each side by 2
(w+14)/2 *2 = 10*2
w+14 = 20
Subtract 14 from each side
w+14-14 = 20-14
w = 6
Answer:

Step-by-step explanation:
Answer:
x = 31.12
Step-by-step explanation:
First find the base (hypotenuse) of the smaller triangle (the isosceles triangle): Its three sides are 11, 11 and b. b can be found using the Pythagorean Theorem: b^2 = 11^2 + 11^2 = 242. Then b = √242, or b = approximately 15.56.
b (which is approximately 15.56) is the shorter leg of the large (right) triangle. The trig function needed to solve for x is the cosine:
adjacent side
cos 60 degrees = ----------------------
hypotenuse,
15.56
which becomes (1/2) = ------------
x
Solving this for x, we get: x = 2(15.56) = 31.12
