Answer:
Step-by-step explanation:
Sum of angle in a triangle = 180°
<A+<B+<C = 180
Given <B = 50°
Substituting into the formula
<A+50+<C = 180
<A+<C = 180-50
<A+<C = 130°
Since the ∆ABC is an acute triangle, the angles <A and <C must be angles less than 90° since acute angles are angles less than 90°
The possible values of <A and <C that will be acute and give a sum of 130° are;
∠A= 58° and ∠C= 72°
∠A= 80° and ∠C= 50°
∠A= 60° and ∠C= 70°
You can see that all the Angles are less than 90° and their sum is 130°
Here you go :) have a good day
If you start at (-3,1) and end up at (0,3), you will have increased x by 3 and y by 2. Thus, the slope of this line is m = rise / run = 3 / 2.
Using the point-slope form of the equation of a straight line, we get:
y - 1 = (3/2)(x+3).
This could be rewritten in other forms:
y = 1 + (3/2)x + 9/2, or y = 2/2 + (3/2)x + 9/2, or y = (3/2)x + 11/2.
