Sagot :
Answer:
B
Step-by-step explanation:
This is an isosceles triangle. So, m∠2 = 43°
5x+ 8 = 43
Subtract 8 from both sides
5x = 43 - 8
5x = 35
Divide both sides by 5
x = 35/5
x = 7
Answer:
Hey! Your answer should be B. 7
Step-by-step explanation:
Congruent triangles mean that two angles equal the same amount. Therefore <2 should equal 43°, but plugging 43 into the equation provided, you're left with 43= 5x+8.
Subtract both sides by 8 and you're left with 35= 5x.
To get X alone, you'd divide both sides by 5, leaving you with 7 = x. Therefore, the answer is B. 7
