Answers:
A) SAS
B) ASA
E) LL
============================================================
Explanation:
Let's go through each possible answer choice
A. We can use SAS because we know that AC = XZ (horizontal sides) is one pair of congruent sides, the angle pairing is C = Z, and the other pair of sides is BC = YZ (vertical sides)
B. We can also use ASA. Note how A = X is one pair of angles, AC = XZ is the middle pair of sides, and C = Z is the second pair of angles. The side is between the angles.
C. We can't use SSS as we don't know AB = XY is true or not. There are no tick marks indicating congruence.
D. We can't use LA here because we don't know the altitudes (LA = leg altitude)
E. We can use LL here because we have two right triangles. The two pairs of legs (AC = XZ and BC = YZ) are congruent based on the tickmarks.
F. We can't use HL similar to the reasoning for choice C. We don't know the hypotenuses are congruent or not. If we knew that AB = XY, then we could use HL (hypotenuse leg).

Answer:
jim is correct, x <em>does</em> equal 7°. justify your answer by putting seven back into the equation. it gives you back that 180 equals 180, therefore it is correct
Step-by-step explanation:
so, all angles of a triangle have to add up to 180;
(15x) + (8x - 11) + (3x + 9) = 180
15x + 8x - 11 + 3x + 9 = 180
add your common numbers
26x - 2 = 180
add 2
26x = 182
divide 26
x = 7
put it back into the equation
15(7) + 8(7) - 11 + 3(7) + 9 = 180
180 = 180
Its important to know the categories of number because its in math
