Answer:
the measure of supplementary angles must add up to 180
Step-by-step explanation:
complementary angles add up to 90°
angles on a straight line are supplementary angles which add up to 180°

Answer:
13.5
Step-by-step explanation:
Applying the sine rule to solve for x
SinA /a = SinB / b = SinC/ c
Sin 34 / x = Sin 27/11
Cross multiply :
11 * sin34 = x * sin 27
6.1511219 = 0.4539904x
Divide both sides by 0.4539904
6.1511219/0.4539904 = x
13.549 = x
x = 13.5
The word in the problem that indicates that a negative sign should be used is "descend"
<h3>
</h3><h3>How many meters did he descend?</h3>
We know that he stops for water breaks four times, and between each water break, he descends 15 meters.
The written equation is:
4*(-15)m = -60m
Why the negative sign is used?
The negative sign is used because the hiker is descending, so its height is decreasing. The word in the problem that indicates that a negative sign should be used is "descend"

Answer: 2,754 students
Step-by-step explanation:
18 / 270= 1/15
(1/15)(41,310) = 2,754 students
Answer: Let x = number of pounds of jelly beans
y = number of pounds of almonds.
Then, 4x + 8y = 33
2x + 3y = 13
Multiply the second equation by -2 to get the system:
4x + 8y = 33
-4x - 6y = -26
Adding the equations, we get 2y = 7. So, y = 3.5
Substitute for y in either of the given equations: 2x + 3(3.5) = 13
2x + 10.5 = 13
2x = 2.5
x = 1.25
ANSWER: a pound of jelly beans costs $1.25 and a pound of almonds costs $3.50.
