Answer:
-44/5 = a
Step-by-step explanation:
- 26 = 8 + 5(a + 2)
Subtract 8 from each side
- 26-8 = 8-8 + 5(a + 2)
-34 = 5(a +2)
Distribute
-34 = 5a +10
Subtract 10 from each side
-34-10 = 5a +10-10
-44 = 5a
Doivide each side by 5
-44/5 = 5a/5
-44/5 = a
P would be (4,1), Q would be (2,-8) and R would be (-8,-1).
In this case, where you are reflecting over the Y axis, you just switch the values of X (from negative to positive and vice versa)! When reflecting over the X axis, you do the same but you switch the Y values from negative to positive (and vice versa).
Hope this helped!
Answer: 90° , 60° and 30° .
Step-by-step explanation:
Given : In a right triangle with a leg of 4 units and a hypotenuse of 8 units.
One angle should be 90°. (A right triangle has a 90° angle.)
Let the given leg is the side opposite to the angle in the triangle.
Then by trigonometry , we have
[Sine of an angle is the ration of the side opposite to the angle and the hypotenuse of a right triangle.]
Also ,
Let x be the measure of the third angle.
BY Angle sum property of triangle , we have
Therefore , the measures of all angles in the triangle : 90° , 60° and 30° .
