Answer:
x=69 degrees
Step-by-step explanation:
The whole angle is 90 degrees. So, you would need to subtract 90 minus 21 to get the degrees of angle x. So, you would get 69 degrees.
Hope I helped!! :)
Sorry if it's wrong! :(
6.8 my dude because if its 3.5%for 20 all u do is divide and den add
7x + 13 = 4x + 11 + 2x + 19
7x + 13 = 6x + 30
X = 17
7(17) + 13 = 132
Angle 3 is 132 degrees
Answer: -5
Step-by-step explanation:
First, if f(x) is equal to f(-2), then that means that in the equation, everywhere it says x, you sub in for -2. It would look like: f(-2)=(-2)^3-2(-2)-1 Put that into your calculator and you sound get -5.
