Answer:
$55.36
Step-by-step explanation:
3/5 = 0.6, so 4 3/5 = 4.6
2/5 = 0.4, so 6 2/5 = 6.4
(4 3/5)/$39.79 = (6 2/5)/x
4.6x = 6.4 × $39.79
x = $55.36
Answer: b₂=2A/h-b₁
Step-by-step explanation:
A =1/2 (b₁ + b₂)h
2A=(b₁ + b₂)h
2A/h=b₁ + b₂
b₂=2A/h-b₁
Answer:
360°
Step-by-step explanation:
We need only remember that the sum of the measures of the interior angles of a triangle is 180°. Angle c and 112° form a pair of "straight angles," so they add up to 180°; as a consequence, Angle c = 180° - 112°, or 68°.
With two of the interior angles now known, we can calculate the third, Angle A: It is 180° less (51° + 68°), or 180° - 119°, or 61°.
That means that the measure of Angle B is 180° - 61° = 119°
Looking at the pair C and 112°, we identify the exterior angle as 112°.
Looking at the pair A and B, or 61° and 119°, we identify the exterior angle as 119°.
Finally, looking at the pair 51° and (180° - 51°), or
51° and 129°, we identify the exterior angle as 129°.
Then the sum of the exterior angles 129° and 119° and 112° is 360°.

Answer:
<em>A. 21°, 69°</em>
Step-by-step explanation:
If you work by process of elimination all you have to do is take 27 away from the bigger degree of the two and see if it is 2x as much as the smaller degree.
Ex.
1. 69°-27°= 42°, which is 2x as many as 21°.
