Answer:
45.6°
Step-by-step explanation:
The attached result was found by typing "arccos(7/10) in degrees" into a web browser search box.
Your calculator can give you the same result. The inverse cosine function often shares a key with the cosine function. It is often marked as cos⁻¹. Be sure that the angle mode is set to degrees, not radians.
Answer:
10
Step-by-step explanation:
distance = √(-6-2)^2+(-2-4)^2
Ans=10
The equation will be 2x + 7 = 3x
subtract 2x from bothsides, you get 7 = x
so x is equal to 7
EDITED
sorry, i didnt read the sum part, so my answer is considered wrong ahaha
2(x+7) equals 3x
distribute, you get 2x+14=3x
then subtract 2x,
the answer for x is 14
Answer:
b)34°
Step-by-step explanation:
3x+50°+2x-30°=180°
5x+20=180° collect like term
5x=180°-20
5x/5=160°/5
×=32°
find M
M=(2x-30°) by Vertical opposite angle
2×32°-30
64°-30°=34°
