Help!!!!!! Easy math problem

Mathematics
1 answer:
pychu [463]3 years ago
5 0

Answer:

x = 6

Step-by-step explanation:

180° is always all triangles.

This is a right triangle, so that means that the angle that is unknown is 90.

Angles:

90

60

7x - 12

90 + 60 + 7x - 12 = 180

150 - 12 + 7x = 180

138 + 7x = 180

7x = 180 - 138

7x = 42

7x/7 = 42/7

x = 6

(a) A square has a perimeter of 60m. What is the length of each side.
sp2606 [1]

Answer:

a. 15m

b. 7m

Step-by-step explanation:

  • perimeter is the sides added up, there are four sides of a square, and all sides are equal
  • equation s+s+s+s or s•4 (s=sides)
  • so to find the length with the perimeter divide perimeter by 4
  • 60/4=15

  • the area of a square is s²
  • so take the square root of the area
  • √49=7
