Which of the following triangles are possible to draw?
1 a triangle with angle measures of 30°, 60°, and 90°.
2 a triangle with angle measures of 20°, 50°, and 105°.
3 a triangle with angle measures of 100°, 40°, and 45°.
4 a triangle with angle measures of 55°, 35°, and 80°.
5 a triangle with angle measures of 25°, 65°, and 90°.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
