A triangle has three angles, and their measures add up to 180 degrees.
An isosceles triangle has at least 2 congruent sides, and the angles opposite the congruent sides are congruent.
This triangle has one angle of 40 deg, and two angles that measure the same; call the measure of each base angle x.
x + x + 40 = 180
2x + 40 = 180
2x = 140
x = 70
The base angles measure 70 deg.
Answer:
false
Step-by-step explanation:
20 - 1 = 1 + 17
Simplify each side.
19 = 18
Since 19 = 18 is a false statement, the equation is false.
Answer:
30
Step-by-step explanation:
- How much was the decrease from Figure A to Figure B (let x be the decrease): 45x = 27
- Divide each by 45 to cancel out the 45 next to x. It should now look like this: x = 3/5
- To find x, we would normally multiply x by 3/5, but because we don't have x, we just DIVIDE 18 by 3/5: 18 ÷ 3/5 = 30
- So, x = 30
I hope this helps!
Answer:
The slope is 17 / 2.
Step-by-step explanation:
The slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.
y=mx+b
Find the values of m and b using the form y=mx+b.
m=17 / 2
b=3
The slope of the line is the value of m, and the y-intercept is the value of b.
Slope: 17 / 2
y-intercept: 3
It would be 90 degrees. :)
