Answer:
-11
Step-by-step explanation:
m + n = - 2
4(m + n) = - 2(4) (multiplying both sides by 4)
4m + 4n = - 8
4m + 4n - 3 = - 8 - 3 (Subtracting 3 from both sides)
4m + 4n - 3 = - 11
Answer:
69.4 degrees.
Step-by-step explanation:
Complementary angles add up to 90 degrees so we have the equation:
4x + 3 + x + 4 = 90
5x + 7 = 90
5x = 83
x = 16.6
The larger angle = 4x + 3
= 4(16.6) + 3
= 69.4 degrees (answer).
Answer: x = 2.8283
Step-by-step explanation:
pythagorean theory or sohcahtoa or sin law
T = 60' and T = 45': S = 90' : T = 45' : R = 90'
t = 3.464
sin law (i can't rlly show u)
q = 3.99
if u don't know what q is, it is the length of the middle line also known as RT
then u do
180 - 45 - 90 = Q
45 = Q
with 45 we can do sin law again
x = 2.8283 is the length of x
