145 = 2x + 15

2x = 130

x = 65 (ANS)

Answer:

65º

Step-by-step explanation:

145º = (2x + 15)º

145º - 15º = 2xº + 15º - 15º

130º = (2x)º

x = 65º

A square garden has a diagonal of 34 ft. Colton wants to put a fence around the entire garden. How much fencing will he need? Round to the nearest foot.

Answers

ok
pythagorean theorem
a and b are legs, c is hypotonuse (diagonal in this problem)
in square, legs are equal
a=b

a^2+b^2=c^2

diagonal is 34
a=b
a^2+a^2=34^2
2a^2=1156
divide both sides by 2
a^2=578
a=17√2

perimiter is 4 time 1 side for square
p=4 times 17√2
P=68√17 feet

aprox 96.1665 feet

Let s be the length of a side.

By the Pythagorean Theorem (or knowledge of 45-45-90 triangles) we can find the length of a side from the hypotenuse.
s² + s² = 34²
2s² = 34²
2s² = 1156
s² = 578

s = √578
s ≈ 24.04

There are 4 sides to the square:
P = 4s
P ≈ 96.16

Answer:
About 96 feet
