Answer:
The sum of interior angles of a regular shape is found by doing no. of sides - 2 and times this by 180
8-2 =6
6x 180= 1080
then divide by 8 to find each angle
1080/8 = 135
Answer:
A = 73.33
B = 53.33
C = 53.33
Step-by-step explanation:
Since they are in a triangle, the sum of the three angles = 180
A + B + C = 180 ••••••(i)
Since B and C are congruent, it means that they are equal;
hence B = C ••••••(ii)
We can rewrite equation i as;
A + B + B = 180
A + 2B = 180 ••••••(iii)
Lastly;
B = A -20 •••••(iv)
Substitute iv into iii
A + 2(A -20) = 180
A + 2A -40 = 180
3A = 180 + 40
3A = 220
A = 220/3 = 73.33
But B = C = A -20 = 73.33 -20 = 53.33
Answer:
<h2>a = 1</h2>
Step-by-step explanation:
The linear function in slope-intercept form:
We have
Therefore <em>a</em> must be equal to 1.
Answer: D) (-5, 1)
<u>Step-by-step explanation:</u>
Inverse is when the x's and y's are swapped.
f(x) has the coordinate (1, -5) --> the inverse of that is (-5, 1), which is option D.
Answer:
5 units up
Step-by-step explanation:
Adding 5 to the y-value of an (x, y) coordinate moves it up 5 units.
f(x) = x^2 +5 is translated 5 units upward from f(x) = x^2.
