Step-by-step explanation:
Multiplying fractions: multiply numerators and multiply denominators
1. 3/4 X -6/7 = -18/28 = -9/14
2. -2/7 X -3/7 = 6/49
3. 4 because 72/9 is 8. -72/-9 is 8. Two negatives makes a positive when multiplying and dividing.

Answer:
v = 87
Step-by-step explanation:
the angle v+39 lies on a straight line. so substract v+39 from 180 to get the interior angle for that side.
afterwards, knowing that the sum of interior angles of a triangle = 180, form an equation with all the angles and solve for v
Answer:
-28

Answer:
Step-by-step explanation:
Triangle PQR is given to be a right triangle, so the Pythagorean Theorem can be used to determine that PQ is the hypotenuse.
It is given that x^2 + y^2 =z^2 in triangle ABC, so AB = PQ.
The information shows that the triangles are congruent because their three sides are congruent. Therefore, to show that triangle ABC is a right triangle, we can use corresponding parts of the congruent triangles to show that BCA is a right angle.
