Check the picture below.
well, since the triangle is an isosceles, with twin sides and twin angles at the "base", let's check what the angle at R is, 15(7) - 31 = 74, and her twin sister at T is also 74, that means that the angle at S is 180 - 74 - 74 = 32.
Answer:
H) B= 13
Step-by-step explanation:
<em>5 + b = 18</em>
<em>F) 5 + 5 = 10 so not equal to 18. It is not a solution</em>
<em>H) 5 + 13 = 18 it's equal . so it is the solution</em>
<em>G) 5 + 8 = 13 so not equal to 18. It is not a solution</em>
<em>J) 5 + 23 = 28 so not equal to 18. It is not a solution</em>
13x - 6y = 2......multiply by 2
3x - 4y = -10....multiply by -3
------------------
26x - 12y = 4 (result of multiplying by 2)
-9x + 12y = 30 (result of multiplying by -3)
-----------------add
17x = 34
x = 34/17
x = 2
now sub 2 in for x into either of the original equations to find y
3x - 4y = -10
3(2) - 4y = -10
6 - 4y = -10
6 + 10 = 4y
16 = 4y
16/4 = y
4 = y
solution is (2,4)
