Answer:
Acute angle
Step-by-step explanation:
Given that m<C = , to find out the type of angle angle C is, evaluate the expression given by substituting x = 13, in the expression.
m<C =
m<C =
m<C =
m<C = 76°
Acute angles are less than 90°.
m<C is less than 90°, therefore it is an acute angle.
Answer:
c = 18.47
Step-by-step explanation:
This would create a triangle in which the length of the wall would be the missing side. We can use the Pythagorean Theorem to find this:
1. +
=
2. +
=
3. 25 + 196 =
4. 221 =
5. = c
6. 18.47 = c
