Isocolese triangle has 2 angles of same length
all angles in a triangle add to 180
so
if the angles are m∠A, m∠B, m∠C, then
either m∠A=m∠B or m∠B=m∠C or m∠A=m∠C
anyway
so if we assume that vertex B is the one that has a twin then
130+130+?=180
260+?=180
?=-80
false, we can't have a negative angle measure
so 130 must be the odd one
?+?+130=180
2?+130=180
2?=50
?=25
so
m∠A=m∠C=25°
let's test the 2nd answer choice
m∠A+m∠B=25+130=155, yep
test 3rd
m∠A+m∠C=25+25=50≠60, nope
not 3rd one
so answer is 2nd statement
<span>m∠A + m∠B = 155° </span>
Answer:
9+2/1. I think not 100% sure tho
Step-by-step explanation:
Wendy = W
Connie = C
Tim = T
Equations
W = C + 4
C = T + 4
W + C + T = 45
Solution
Put W into the third equation
C + 4 + C + T = 45
2C + 4 + T = 45
Put T into the above equation
C = T + 4
T = C - 4
2C + 4 + C - 4 = 45
3C = 45
C = 15
C = T + 4
15 = T + 4
11 = T <<<< Answer
