HI PLEASE HELP 16 POINTS
(will give brainliest for actual answer)

Drivers of semitrucks and other large vehicles pay close attention to signs similar to the one below. These signs indicate a change in the grade or slope of the road. Look at the black scalene triangle in the sign.
1. How can the third-angle theorem be applied to find all three angle measurements in the black triangle?
2. Are the black triangles above congruent or similar? Explain.

(image below)

a triangles angles equal 180 so add 90 and 60 then subtract that from 180. 2) yes. they have same angles so they must be congruent

Step-by-step explanation:

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
