Question 1:
We can use the rule of exterior angle of triangle, where the exterior angle is equal to the sum of the other 2 interior angles of the triangle except for the adjacent one.
So, we can calculate angle 1 by adding up the 2 given angles.
Angle1 = 62° + 57°
=119°
=answer C.
Question 2:
We can also apply the rule above, but first we have to calculate the remaining angle of the triangle first.
For this, we have to use the angle sum of triangle. All 3 interior angles of triangle should add up to 180°.
Let that remaining angle be x.
X = 180° - 62° - 57°
X=61°
Now we can apply the rule of exterior angle of triangle.
Angle 1 = 62° + 61°
=123°
=answer D.
Answer:
18 t-shirts.
Step-by-step explanation:
Trey made a total profit $106 by selling t-shirts and hats. $34 of that profit was from selling hats, subtract 34 from 106 and you will get 72. So he made a profit of $72 in selling t-shirts. The t-shirts were $4 each, so if you divide 72 by 4 you will get 18. Meaning he sold 18 shirts.
After dilation by a scale factor of 2 we get the result (-8, 10).
What is the scale factor?
When describing a shape, you must be clear about how much it has been enlarged.
The ratio of two dimensions that causes one figure to be enormous and another to be little is known as the scale factor.
Given coordinate (-4, 5)
If any general coordinate (x, y) is scaled by 2 then we get
X= 2x and Y = 2y
Hence, X= 2 * -4, where x = -4
=> X= -8
and Y= 2 * 5, where y = 5
=> Y = 10
Therefore, the required result is (-8, 10).
