Answer:
is there a chart?
Step-by-step explanation:
Answer:
- 78.33°
- 71°
Step-by-step explanation:
1) The sum of angles in a triangle is 180°, so ...
(x +3)° +(x +24)° +(x -10)° = 180°
3x +17 = 180 . . . . . . . . divide by °, collect terms
3x = 163 . . . . . . . . . . . .subtract 17
x = 54 1/3 . . . . . . . . . . .divide by 3
m∠B = (x +24)° = (54 1/3 + 24)°
m∠B ≈ 78.33°
__
2) An exterior angle is equal to the sum of the opposite interior angles.
m∠ACD = m∠A + m∠B
(3x -10)° = (x +9)° + 105°
2x = 124 . . . . . . . . . . . . . . divide by °, add 10-x to both sides
x = 62 . . . . . . . . . . . . . . . . divide by 2
m∠A = (x +9)° = (62 +9)°
m∠A = 71°
Answer:
hi
Step-by-step explanation:
100+20 is equal to 120
have a nice day
6x = 48
180/z = 90
10y + 8 + 138 = 180
<span>The form of a linear equation that shows the slope and one point is the POINT-SLOPE FORM.
</span>Equations in point-slope form<span> look like this: y - k = m(x - h) where m is the </span>slope<span> of the line and (h, k) is a </span>point<span> on the line (any </span>point<span> works). To write an equation in </span>point-slope form<span>, given a graph of that equation, first determine the </span>slope<span>by picking two </span>points<span>.
