Answer:
120 Degrees
Step-by-step explanation:
Angle T and R are vertical angles meaning they are equal so combine the equations: 31x - 4 = 29x + 4, then solve using inverse operations
subtract 31x from both sides to get -4 = -2x + 4
Then subtract 4 from both sides to get -8 = -2x, now that we have isolated the variable we have to divide by -2 on both sides getting us x = 4, then plug in the four to the equation for angle R getting you 29 times 4 which equals 116 + 4 = 120
Answer:
51
Step-by-step explanation:
Multiply 3 2/5 by 15
Change the mixed number to an improper fraction
3 2/5 = (5 * 3 + 2) /5 = 17/5
17/5 * 15
17 * 15/5
17 * 3
51
Ok 12÷9=0r12 and with exponits 10 and 10 because 10 and 10 will become 10 and 6 so 12+10=22 now you can divide 22÷9=1R3
