Vrect = base × height (h) = s^2×h
Vrect = 175 in^3, h = 7in.
s^2×h = 175
7s^2 = 175
7s^2/7 = 175/7
s^2 = 25
SR(s^2) = SR(25)
s = 5 in.
5-12 ÷(6-2)-1
Do whats in the parenthesis
5-12 ÷4-1
Do division next
5- 3- 1 = 1.
Do the same for the next.
(4-3) x 2+15 ÷(6-1)
1 x 2+15 ÷5
2+15÷5
2+3= 5
Answer:
Options (A), (B)
Step-by-step explanation:
Option A.
Two sides of the given triangle are equal. Therefore, the given triangle is an isosceles triangle.
Option (B).
Given triangle has a right angle. Therefore, it's a right triangle.
Option (C).
Only two sides of the given triangle are equal. Therefore, it's not an equilateral triangle.
Option (D).
Although this triangle has two acute angles (less than 90°) but the third angle is 90°. Therefore, this triangle is not an acute triangle. It's a right triangle.
Option (E).
A scalene triangle is a triangle having all sides different in measure but the given triangle is an isosceles triangle. Therefore, it's not a scalene.
Option (F).
Any angle of this triangle is not more than 90°. Therefore, the given triangle is not an obtuse triangle.
angle x would end up being equal to 71 degrees.
Answer is 129(A) hope this helps:)
