Answer:
Step-by-step explanation: 18 * 50 = 900
738/900 = .82
Move two decimal to right .82 = 82%
-3(5-6)-4(2-3)
Handling parentheses first:
-3(-1)-4(-1)
Multiplication left to right:
3-4(-1)
3-(-4)
Rewriting the above we have:
3+4=7
A right triangle has a perpendicular corner in it. This means that one of its angle has a measure of 90 degrees. The sum of all angles in the triangle is 180. To determine the acute angle, or more importantly, the last missing angle, it would be,
180 = 90 + 63.7 + x
x = 180 - 90 - 63.7
x = 26.3 degrees
This is an acute angle because it is less than 90. So, the answer is 26.3 degrees.
I believe it is 4 hope this helps!
