Answer:
x=11
Step-by-step explanation:
Using the Exterior Angle Theorem. . .
(3x+8) + (2x+9) = (8x-16)
Solve to get x = 11
The three inside angles of a triangle need to equal 180 degrees.
This means X = 180 - 43 - 59 = 78 degrees.
X and Z make a straight line that also needs to equal 180 degrees,
so Z = 180 - 78 = 102 degrees.
Y = 180 - 102 - 13 = 65 degrees.
5/8÷8=5/8×1/8
5/64 is the answer
10^2 + b^2 = 26^2
100 + b^2 = 676
-100 -100
b^2 = 576
square root of b equals b
square root of 576 equals 24
The other leg equals 24
3b+2-b=-18
2b+2=-18
2b=-20
b=-10
