Answer:
RSQ is 105° and RPQ is 30°
Step-by-step explanation:
since S is the incenter of PRQ and RQP the angles are divided by 2
then use angle sum property that is 45+30+s=180
75+s=180
s=180-75
s=105
Answer:
It says double, so it means that:
_____ x 2 = 50
In order to find _____, you must reverse the equation.
50 / 2 = _______
This means that:
50 / 2 = 25
So, ______ = 25
Answer:
-7/3
Step-by-step explanation:
slope formula:
y = mx + b
the m is the slope value
Answer:
y < 3/2x - 5/2 or y < 3/2 x - 2.5
Step-by-step explanation:
3x -2y > 5
Solve for y
3x - 2y > 5 when solving a problem with an inequality sign, rewrite the problem and solve with an equal sign and add the equality at the end.
3x - 2y = 5
-2y = -3x + 5
y = -3/-2x+ 5/-2
y = 3/2x - 2 1/2
Now if you have to use the inequality sign, you will use < because the y term was negative and that will change the direction of the inequality sign.
So y < 3/2x - 5/2 or y < 3/2 x - 2.5
5)
x = 132 - 42
x = 90
Answer
90 degrees, right angle
6)
180 - 126 = 54
The other two are congruent so 54/2 = 27
Answer
27
7)
An exterior angle of a triangle is equal to the sum of the opposite interior angles
So
6x = 38 + 82
6x = 120
x = 20
Answer
20
8)
Sum of interior in a triangle = 180 degrees
So
2x - 3 + 23 + 128 = 180
2x + 148 = 180
2x = 32
x = 16
Answer
16
