Answer will be 2 i hope this help
Answer:
Step-by-step explanation:
*Notes (clarified by the person who asked this question):
-The triangle on the right has a right angle (angle that appears to be a right angle is a right angle)
-The bottom side of the right triangle is marked with a question mark (?)
<u>Triangle 1 (triangle on left):</u>
Special triangles:
In all 45-45-90 triangles, the ratio of the sides is , where is the hypotenuse of the triangle. Since one of the legs is marked as , the hypotenuse must be
It's also possible to use a variety of trigonometry to solve this problem. Basic trig for right triangles is applicable and may be the simplest:
<u>Triangle 2 (triangle on right):</u>
We can use basic trig for right triangles to set up the following equations:
,
We can verify these answers using the Pythagorean theorem. The Pythagorean theorem states that in all right triangles, the following must be true:
, where is the hypotenuse of the triangle and and are two legs of the triangle.

Answer:
y=3/4x+2
Step-by-step explanation:
The slope intercept formula is y=mx+b
b=2 because it is the y intercept
m is the slope
from (0,2) I counted how many points over and up the next point directly on the two lines was , which was point (4,5)
it was 4 to the right and 3 up
slope is rise over run so the slope is 3/4
