Answer:
D)99 degrees
Step-by-step explanation:
The answer is D. All the angles in any quadrilateral add up to 360 degrees. And since the figure is a paralledlogram, for each angle there is another angle with the same measurement. So 81 + 81 + x + x = 360 which gives us 162 + 2x = 360. If you solve for x you get 99 degrees.
The correct option is (A) AB 162°
Explanation:
A minor arc is an arc of a circle having measure less than or equal to 180° or π radians. From the options given above the arc which has a measure less than 180° is AB.
Information: ADB 198° is the major arc as its central angle is greater than 180°.
The correct option is (A).
-i
The simplified expression are as follows;
6mn³ - mn² + 3mn³ + 15mn² = 9mn³ + 14mn²
a⁴b³ + 8a⁴b³ = 9a⁴b³
<h3>How to simplify an expression?</h3>
A simplified expression is express to its lowest term.
Therefore,
6mn³ - mn² + 3mn³ + 15mn²
combine like terms
6mn³ + 3mn³ - mn² + 15mn²
9mn³ + 14mn²
a⁴b³ + 8a⁴b³ = 9a⁴b³
