12,390 ft above see level! I am positive and sure this is the right answer...if not please somebody correct me!
Answer:
Pythagorean Theorem : a²+b²=c²
a²+38²=42² => a²=1764+1444 => a²=3,208 inch => a=√3,208
=> a=56.64 inch
Step-by-step explanation:
2 x B + 4 = -8
-4 -4
2 x B = -12
divide by 2 on both sides
B = -6
Answer:
False.
Perpendicular intersect to make a right angle.
Answer:
3 = 21 degrees
5 = 21 degrees
1 = 60 degrees
2 = 39 degrees
4 = 39 degrees
Step-by-step explanation:
This problem is really quite easy once you break it down. I assume you want an answer based on the attachment. If a triangle is Isosceles, then its bottom two angles are congruent, so angle 3 = angle 5.
Then, 138 degrees + x * 2 = 180 degrees.
x * 2 = 42 degrees
x = 21 degrees
So 3 and 5 are each 21 degrees
If a triangle is equilateral, then it is also equiangular, meaning each of its angles are equal to each other, and they are each 60 degrees. Then, we know angle 1 is 60 degrees. For 2 and 4, we want to take the measure of the combination of 2 and 3 (the full 60 degrees), and subtract it by the measure of angle 3 to get the measure of angle 2. 60 - 21 = 39 degrees. Angle 2 is 39 degrees. The same can be done with angle 5 and 4 because they are the same measurements.
