Can you help with this please?​
insens350 [35]

Answer:

A

Step-by-step explanation:

the answer is A. if you notice the y-intercept, it its at -5

A is the only answer choice that gives -5 as the y-intercept

another way to make sure that A is the right answer is to calculate the slope

when you increase 3 units UP (y), you increase 5 units to the RIGHT (x)

since slope is y/x, it should be 3/5 which is also in A

another way to check A is to plug in points

hope this helps!

Answer:

Top question: -7°

Bottom question : 18°

Step-by-step explanation:

Top question:

The base angles of am isosceles triangle are congruent:

x + 46 = 39 because the base angles of an isosceles triangle are congruent

x + 46° = 39°

x = -7°

Bottom question

The missing angle is 3x because the base angles are congruent

To find the value of x, we must add all the angles inside the triangle, and find the value of x that makes it equal to 180°

3x + 3x + 4x = 180°

10x = 180°

x = 18°

Sorry for the late post!
