Answer:
we need the diagram
Step-by-step explanation:
the adjacent angles in a parallelogram
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.
Answer:
x=-4
y=-4
Step-by-step explanation:
We are going to eliminate the variable x. In order to do this, we are going to make the coefficients the same by multiplying the second equation by 2

Answer:
The length of the slide he needs to make = AC = L = 14.3 ft
Step-by-step explanation:
From the Δ ABC
AC = Length of the slide = L
AB = 9 ft
°
From Δ ABC
Put all the value in the above formula
L = AC = 14.3 ft
Therefore the length of the slide he needs to make = AC = L = 14.3 ft
