You have been reading your book for about 7 days
7(10) pages each day + 9 left
70+ 9 = 69
Expressions are problems with no answer. I would use it to represent inequalities and/or a basic formula
Answer:
A
Step-by-step explanation:
2 is the only acute angle meaning less than 90 degrees.
225, the square root of 225 is 15
That is not a trapezoid, it is a general quadrilateral. All 2-dimensional, 4-sided figures have an internal angle sum of 360 (triangles are 180). So if you assume angles P and Q are right, they are each equal to 90 degrees, for a total of 180.
Subtract: 360 - 180 = 180. We know that S + R must equal 180. If you subtract 180 - 65, you get 115, which is obtuse (greater than 90 degrees). This matches the drawing as the unknown angle is clearly greater than 90. So the answer is 115 degrees.
