Answer:
<h2>Supplementary angles</h2>
Step-by-step explanation:
Supplementary angles add up to 180°.
m∠VST = m∠VSW + m∠TSW
m∠VST = 180° → m∠VSW + m∠TSW = 180°
Answer:
a) Exterior Angle Theorem
b) x = 109°
Step-by-step explanation:
For a, you can thank the Exterior Angle Theorem. Since the angles of a triangle equal 180°, we can figure out what the third interior angle's measurement is, then subtract that from 180 to get the exterior angle's measure. Since the two angles labeled (64° and 45°) will make an obtuse angle, then the third interior is an acute angle. Add 64 and 45 to get the exterior angle's measurement of 109 degrees. That would mean the third interior angle's measurement would be 71 degrees. 64 + 45 + 71 = 180, so this is true.
(I had used the HSEAT to explain this.)
Answer:
7
Step-by-step explanation:
Answer:
x -intercept (31,0)
y-intercept (0,-31/10)
Step-by-step explanation:
x-10y=31
x-10(0)=31
x=31
x-10y=31
0-10y=31
-10y=31
y=-31/10
Answer:
The slope-intercept equation:
Step-by-step explanation:
Since you already have the <u>y-intercept</u> and the <u>slope,</u> use the <u>point slope Formula</u> to help you solve and get it in <u>slope-intercept form</u>:
-Apply both the <u>y-intercept</u> and the <u>slope</u> for the formula:
-Then, solve the equation:
-Result:
