In a right triangle, the measure of one acute angle is 30 less than twice the measure of the other acute angle. Find the measure of each angle.
---
The sum of the 2 acute angles is 90 degrees.
x + y = 90
x = 2y-30
----
Substitute for "x" and solve for "y":
2y-30 +y = 90
3y = 120
y = 40
x = 90-y
x = 90-40
x = 50
Answer:
so the slope of the line would be -2/-3
Step-by-step explanation:
6-8
= -2/-3

Answer:
x = 28 649/700
Step-by-step explanation:
Add 780/28.
1.07 +780/28 = x
x = 28 649/700 = 28.92_714285(repeating)
_____
If one were concerned with significant digits, one could argue that the value should be rounded to 28.93, the precision of 1.07.
Answer:
2 * 2 * 2 * 2
2^4
Step-by-step explanation:
16= 4 * 4 = (2 * 2) * (2* 2)
(3 - 0.49) / 3 = 2.51/3 = 0.836 = 83.6% is saved
