7x^4 - 5x^4 = 2x^4
if the base (x^4) is the same, you can just subtract the coefficients
Answer:
128°
Step-by-step explanation:
<u>The measure of an inscribed angle is half the measure of the intercepted arc.</u> That means that the intercepted arc is two times the inscribed angle.
Measure of the inscribed angle DEF is 64°, that means that the measure of the intercepted arc DF is 2×64°, which is 128°.
5. We can see that angle a is the same angle as the 130° angle, since they form a Z. The same goes for b and 65°. a° = 130°, b° = 65°
6. With the same Z angles, b° = 56°. Because the angles are parallel, a° = 124°
7. Because the angles are parallel, b° = 83°, and a° = 132°
8. Because the angles are Z angles, a° = 74°. Because a° and b° are supplementary angles, b° = 180° - 74° = 106°. Because c° and 74° are supplementary angles, c° = 180° - 74° = 106°. Because d° and 65° are parallel angles, d° = 65°. Because d° and e° are opposite angles, e° = 65°
I'm not 100% sure what the question wants as its answer, but having a class of 26 students is around the average number of students in a class.
