Find the value of each variable. Round to the nearest tenth. How does the measure of angle x compare to the measure of angle z?

monitta

Answer:

z = 47.2°

w = 42.8°

y = 42.8°

x = 47.2°

Step-by-step explanation:

found altitude ('h') first: 6/h = h/7; h = $\sqrt{42}$

found base by using Pythagorean Theorem:

7² + ( $\sqrt{42}$ )² = c²

c = $\sqrt{91}$

found angle z using Rule of Sines:

sin 90 / $\sqrt{91}$ = sin z / 7

arcsin z = 7 / $\sqrt{91}$ = 47.2°

found angle w by adding 90 and 47.2, then subtracting from 180 to get 42.8°

found angle y by subtracting m∡z from 90° to get 42.8°

found angle x by adding 90 and 42.8°, then subtracting from 180

Urgent math help needed 2 questions!

5. Basically you need to add the terms in the same positions in both matrices, so:

2 + 6 = 8 1 + (-4) = -3
-3 + 2 = -1 0 + 4 = 4

So the answer would be the first one :)

6. This one is not possible as to add or subtract matrices they must have the same order, which is not the case with this pair.
