Hi !
For example,if you have 3π/4 that means you have 3*180°/4=135 degrees
Because: π=180° so you just have to replace π to 180°
Vice vers:you just have to replace 180° to π
For example:What it means 225°?
225°=270°-45°
=3*180°/2 - 180°/4
=3π/2- π/4
=(6π-π)/4
=5π/4
Answer:
the answer is b and I'm sure but please mark me brainlest
Answer:
3x^2-4
Step-by-step explanation:
f(x) = 2x² + 3 and g(x)=x²-7
(f+ g)(x) = 2x² + 3 + x²-7
Combine like terms
= 2x^2+x^2+3-7
=3x^2-4
Answer:
x ≈ 3.7 m
Step-by-step explanation:
Use the right triangle on the left to find the height h , using the sine ratio
sin39° = = ( multiply both sides by 7 )
7 × sin39° = h , then
h = 4.4
Using the tangent ration on the right side right triangle, then
tan50° = = = ( multiply both sides by x )
x × tan50° = 4.4 ( divide both sides by tan50° )
x = ≈ 3.7 m ( to 1 dec. place )
Answer:
about 24%
Step-by-step explanation:
1/2 times 9/19
0.5 times 9/19
is about 0.24
0.25 mean about 24%
