Answer:
x=12.
Step-by-step explanation:
Let's get this straight out of the way, the 3 angles of a triangle ALWAYS add up to 180. Now that that's said, lets begin. Since the opposing side of an angle is the same as the regular side, we simplify to get: 5x+120=180. 180-120=60. so 5x=60. 60/5=12. so x=12.
-5.25 to the nearest tenth is -5.3.
Answer:
AB is congruent is CD. (Last one)
Step-by-step explanation:
Hypotenuse leg is when the hypotenuse and ONE (you only need one, not two) leg of the triangle are congruent in a RIGHT triangle.
In the image, you already know that it is a right triangle and you know that the hypotenuse are congruent (Reflexive Prop) .You just need to know that the legs are congruent. So you choose which one has the legs congruent. The leg pairs that can be congruent are AD and CB or DC and AB. The only one that matches this is the last one
Given:
A figure of triangles.
To find:
Whether the triangles SPT and triangle QPR are similar.
Solution:
In triangle SPT and triangle QPR,
(Given)
(Common angle)
In triangles SPT and triangle QPR, two corresponding angles are congruent. So, by AA property of similarity both triangles are similar.
Therefore, yes, the triangle SPT and triangle QPR similar. Option A is correct.
