Find the missing angle according to the Triangle Sum Theorem.

Mathematics
1 answer:
dangina [55]3 years ago
4 0

Answer:

k = 140 degrees.

The missing INTERIOR angle is 40 degrees.

Step-by-step explanation:

The missing interior angle would be 40.

Triangle angle sum theorem states the 3 interior angles of a triangle sum to 180.

64+76+40 = 180

The exterior angle theorem states the exterior angle of a triangle is equal to the sum of the two remote interior angles of the triangle.

Exterior angle k = 64+76

k= 140

prohojiy [21]
<span>To find the answer to this equation, use the result of "27 people" who prefer tea. This is equivalent to 3 out of 10 people in the whole survey sample. Using equivalent fractions to find the total sample, we see that "3/10 = 27/x." Multiplying 3 by 9 gives 27, so multiplying 10 by 9 gives a total sample size of 90 people.</span>

The area of a circular place is 45 square inches. Estimate the radius to the nearest integer.
aksik [14]
A=pi(r)^2
45=pi(r)^2   divide by pi (3.14)
14.33=r^2   square root both sides
3.79=r         round
r=4

I need some help please!<br> K is the midpoint or segment JL. JL=3x-15 <br> JK=18<br> Find x.
vazorg [7]

Because K is the midpoint of JL and JK = 18, KL must also equal 18. So the equation would be 3x - 15 = 36 because you add 18 + 18. You then add 15 to both sides to get 3x = 51. Then you divide by 3 on both sides to get x = 17.
