Answer:
B.
Step-by-step explanation:
if smart, they can hide
4^2 + 7^2 = c^2
This is because we know that the hypotenuse (c) is always diagonal to the right triangle, so the legs are 4 and 2 (a and b). There is your equation!
Good luck!
Answer:
119°
Step-by-step explanation:
the angles of a triangle make 180° (so does a straight line) therefore
180 (triangle) = a + c + 51
to find c:
180 (straight line) = 112 + c
c = 180 - 112
c = 68°
now we have
180 (triangle) = a + 68 + 51
to find a:
a = 180 - (68 + 51)
a = 180 - 119
a = 61°
to find b:
180 (straight line) = 61 + b
b = 180 - 61
b = 119°
3x - 13 = 7(x + 2) - 4(x - 7)
3x - 13 = 7x + 14 - 4x + 28
3x - 13 = 3x + 42
3x = 3x + 55
0 = 55
0 ≠ 55
so…
answer: no solution
