F=1.8C+32
We are given C=-20 degrees
plugging this value in the given equation
F=1.8(-20)+32
F=-36+32=-4
F=-4 degree fahrenheit
m_6 + m_8 = 180º because they form a straight line.
So, (2x-5) + (x+5) = 180
3x = 180
x = 60
So, m_115º (2•60 - 5 = 115)
Also, because the two lines are parallel m_6 = m_3 by alternate interior angles.
So, m_3 = 115º
Answer:
D. 54
Step-by-step explanation:
Right angle = 90°
3/5 of 90°
3/5 × 90°
270 ÷ 5 = 54°
