Answer:
D = 90°
E = 147°
F = 33°
Step-by-step explanation:
E:
E is 147°, because it is vertical to the angle 147°
F:
F is 33°, because 147* is its supplementary angle, or angles that add up to 180°
D:
D is worth 90°, because its supplement is worth 90°

Answer:
The actual distance between the cities is 211.67 cm.
Step-by-step explanation:
Given:
The map key indicates that 4.5 cm is equivalent to 75 cm.
Now, to find the actual distance between the cities if the cities are 12.7 cm apart on the map.
Let the actual distance be
.
So, we set a proportion to find the actual distance:
4.5:12.7 = 75:x.
<em>Changing into fractions.</em>

<em>By cross multiplication we get:</em>

<em>Dividing both sides by 4.5 we get:</em>

Therefore, the actual distance between the cities is 211.67 cm.
Answer:
450
Step-by-step explanation:
you divide 90 by 20 and times in by 100

20 hundreds =20*100=2000;
this is two thousand, so it is made of 2 thousands.</span></span>
(b - 4z)/7 = a
b - 4z = 7a
b = 7a + 4z
Answer: b = 7a + 4z
