Answer:
By substituting x and y vars with that in (x, y)
Step-by-step explanation:
2 * (-3) + 3 * 4 = 6 solution
2 * 0 + 3 * (-2) = -6 not solution
Answer: the exponent is 2
Step-by-step explanation: this is equal to (1/7)^2
91 is 130% of what number...
91 = 1.3x
91 / 1.3 = x
70 = x
so 91 is 130% of 70 <==
Answer:
a) 150°
b) 30°
Step-by-step explanation:
It is easier to work the exterior angle first.
<h3>b)</h3>
The sum of exterior angles is 360°. The exterior angle at any vertex of a regular dodecagon will be 1/12 that:
360°/12 = 30° . . . the measure of one exterior angle
__
<h3>a)</h3>
The measure of an interior angle will be the supplement of the adjacent exterior angle.
180° -30° = 150° . . . the measure of one interior angle
The answer choice should be D
