Answer:
Step-by-step explanation:
4 goes into 64 sixteen times. 64/4 = 16 16 x 4 = 64
An obtuse angle is an angle that is in between 90 degrees and 180 degrees. It looks like this
The last one is not scientific notation because the 25.67 is greater than 10
Answe
Step-by-step explanation:
The interior angles of a triangle add up to 180. We know from the photo that there is a 90° angle and an 18° angle, and 90-18 is 72, so the other interior angle is 72°. The question is asking you to find the value of side x, so you'll need to use sin.
sin (72°) = x/16
x ≈ 15.2
