Answer:
E - 40°
Step-by-step explanation:
Angle O = 2 × y
{Angle at center is equal to twice the angle at circumference formed by the same arc}
O = 2 × 70°
O = 140°
x + 90° + 90° + O = 360°
{Sum of angles in a quadrilateral is equal to 360°}
x + 90° + 90° + 140° = 360°
x + 320° = 360°
x = 40°
Answer:
65,000
Step-by-step explanation:
6 1/2
= 13/2
= 6.5
6.5 * 10,000
= 65,000
Answer:
a^8 - 12a^4 + 36
= (a^4)^2 - 2*a^4*6 + 6^2
= (a^4 - 6)^2
So it’s:
(4/7)x - 5 = -13
Add 5 to both sides
Multiply both sides with 7
Divide both sides with 4
Multiply and dividing is always last!!!
