Answer:
C:108+4x+4=180
Step-by-step explanation:
The angles are supplementary so they sum up to 180
0.75x-18.5=0.65x
0.75x-0.65x=18.5
0.1x=18.5
x=18.5/0.1=185
Answer: x=185
To checkt:
0.75(185)-18.5=138.75-18.5=120.25
0.65(185)=120.25
Step-by-step explanation:
So triangles have 180 degrees total and you have the measure of two angles so you can solve for the third.
T + 41+ 90= 180 add together 41 and 90
T + 131 =180 subtract 131 from 180
T = 49
So the measure of angle T is 49 degrees
