Answer:
z = 72°
Step-by-step explanation:
Complimentary angles sum to 90° , thus
z + y = 180, that is
z + 18 = 90 ( subtract 18 from both sides )
z = 72°
Answer:
? = 113
Step-by-step explanation:
The angles are alternate interior angles. Alternate interior angles are equal if the lines are parallel. Since the lines are parallel, the angles are equal.
? = 113
Answer:
150.8 m³
48π m³
Step-by-step explanation:
V = πr²h/3
V = π · 4² · 9/3
150.8 m³
Answer:
The answer is a no solutions.
Step-by-step explanation:
Answer:
a) x = 12
b) right triangle
Step-by-step explanation:
a) 2x + 1 + 5x + 5 + 90 = 180
7x + 96 = 180
180 - 96 = 84
84 / 7 = 12
x = 12
b) you can tell that it is a right triangle because of the square in the corner that indicates it is a right triangle
