R=I+6 S=4R I
I+(I+6)+4(I+6)=126
Basic algebra (I dont know how to show it) leaves you with: 6I = 90, divide both sides by 6 and I=15
Answer:
AA similarity
Step-by-step explanation:
Respective angles of both triangles are 40°, 50° and 90°
AA similarity is the case:
- <em>If two angles of one triangle are respectively equal to two angles of another triangle, then the two triangles are similar.</em>
Answer:
Angle T would be 70 degrees and angle R would be 110 degrees
Step-by-step explanation:
Since supplementary angles are equal to 180, we can model the angles with the measure below and then add together to get equal to 180.
Angle T = x
Angle R = 2x - 30
x + 2x - 30 = 180
3x = 210
x = 70
Now we know that Angle T is equal to 70 and we can use that to find the measure of Angle R
Angle R = 2x - 30
Angle R = 2(70) - 30
Angle R = 140 - 30
Angle R = 110
