Answer:

76

Step-by-step explanation:

decagon = 10 sides

3 heptagons = 3 × 7 = 21 sides

3 nonagons = 3 * 9 = 27 sides

3 hexagons = 3 * 6 = 18 sides

10 + 21 + 27 + 18 = 76 sides in total

Question 4
lyudmila [28]

Answer: The measure of a central angle is twice as big as the measure of an inscribed angle IF they intercept the same arc on a circle

Step-by-step explanation: See photo. A central angle’s vertex is at the center of the circle. The measure of a central angle is equal to the measure of the included arc. An inscribed angle’s vertex lies on the circle. The measure of an inscribed angle is equal to half the measure of the included arc. Therefore the measure of the central angle is double the measure of the inscribed angle that intercept the same arc on a circle

What equation can be used to find the value of x
Gnom [1K]

Answer:

3x + 1 + 5x - 7 + 11x - 4 = 180°

x = 10°

Step-by-step explanation:

Sum of angle in Triangle = 180°

So lets add up the angles with combining like terms.

3x + 1 + 5x - 7 + 11x - 4 = 180°

19x + 1 - 7 - 4 = 180°

19x - 10 = 180°

19x = 190

x = 10°

If my answer is incorrect, pls correct me!

Can some one help me in this :)
nadezda [96]

Answer:

16m/s

Step-by-step explanation:

distance travelled from L to M = 6 x 10 = 60m

distance travelled from M to N = 160 - 60 = 100m

time taken to travel from M to N = 100/25 = 4 seconds

average speed = total distance / total time = 160m / (6 + 4) seconds = 16m/s

hope that helps!

this is a question on speed, distance and time. I have a formula for it up in my insta page (learntionary) if you need it :)
