Answer:
12
Step-by-step explanation:
Square root of 21 is
<span>4.58257569496
</span>
I rounded it to 4.58
Congruent sides have congruent angles so
w=70
Triangle angles =180 so
70+70+x=180
140+x=180
-140 both sides
x=40
supplimentary angles (angles that make up a line) =180 so
w+y=180
70+y=180
-70 both sides
y=110
triangle angles =180 so
110+25+z= 180
135+z=180
-135 both sides
z=45
w=70
x=40
y=110
z=45
Answer: (x−7)2+y2=100. Explanation: the standard form of the equation of a circle is.
Step-by-step explanation:
We know that
the points where the graph of the function crosses the y-axis is when <span>a function is evaluated with a zero, these points represent the y-intercept of the function
</span>
therefore
the answer is
Represent the y-intercept of the function
