Answer:
x=6
Step-by-step explanation:
4x+13=3(x+6)+1
4x+13=3x+18+1
4x+13=3x+19
-13 -13
4x=3x+6
-3x -3x
x=6
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
-60 plus 22 is -38 and -38 divided by 8 is -4.75
8(-4.75)-22=-60
So X equals -4.75
