90 = 20 + 70.....GCF of 20 and 70 is 10
90 = 10(2 + 7) <==
can u write another expression using a different common factor...yes
90 = 20 + 70.....common factor is 5
90 = 5(4 + 14) <==
Answer:
84°
Step-by-step explanation:
since the opposite side looks identical to the first angle, the second would be the same degrees.
5π/12 = (5 · 180°) : 12 = 75°
cos 75° = cos ( 45° + 30° )= cos 45° cos 30° - sin 45° sin 30° =
=√2/2 * √3/2 - √2/2 * 1/2 =

=(2.4495 - 1.4142): 4 = 0.258825
Answer:
if y is -2, your answer is x = -1
if x is -2, your answer is y = -4
Step-by-step explanation:
If x is -2,
y = 2 (-2)
y = -4
<em><u>But</u></em>
If y is -2
-2 = 2x
x = -2/2
x = -1
