Hello from MrBillDoesMath!
Answer:
Choice A
Discussion:
As the lines are parallel, corresponding angles are equal. This means that
angle x (just to the left of the letter a) and its corresponding angle ( just above line b -- above the the "2x" value shown) are equal..
In other words,
x = 180 -2x
as there is 180 degrees in a straight line.
Add 2x to both sides of the equation:
x + 2x = 180 - 2x + 2x =>
3x = 180 =>
x = 60

Answer:
5/7
Step-by-step explanation:
You find a slope by using the equation y2-y1/x2-x1.
In this case: 15-5/21-7
10/14
5/7
Answer:
if 90% = $36
100%= ?
<u>100%×$36</u>
<u> </u><u> </u><u> </u><u> </u>90%
<u>3600</u><u> </u>= $40
90
Step-by-step explanation:
you use the method of cross multiplying
Let "x" be the longest side and "y" be each of <span>remaining sides
If the triangle is </span>аcute<span> then:
</span>y² + y² > x² <span>
2y</span>² > 8²
2y² > 64
y² > 32
y > √32
y > 5.6 ← <span>to the nearest tenth
</span>
This means the length of each of the remaining sides is more than 5.6 cm, so <span>the smallest</span> possible length of one of the two congruent sides is 5.7 cm.
