Solve for x. hint:half circle.

Mathematics
1 answer:
Romashka [77]3 years ago
4 0

Answer:

x = 10

Step-by-step explanation:

Given

The attached circle

Required

Find the measure of x

From the attached image:

11x + 2 and -2 + 7x form a semi-circle

So:

11x + 2 -2 + 7x = 180

Collect like terms

11x  + 7x = 180+ 2 -2

18x = 180

Solve for x

x = \frac{180}{18}

x = 10

Angle e measures 126LaTeX: ^\circ∘. What is the measure of LaTeX: \angle∠h?
Oksana_A [137]

Option C: 126° is the correct answer

Step-by-step explanation:

When two lines intersect, the four angles are formed. The angles vertically opposite with same vertex are called vertical opposite angles.

The opposite vertical angles are equal.

In the given figure, the pairs of vertically opposite angles are e,h and f,g.

Given

∠e = 126°

The measurement of e and h will be equal as they are vertically opposite

So,

m∠e = m∠h

m∠h = 126°

Hence,

Option C: 126° is the correct answer

Keywords: Vertical angles, lines

Find the value of each variable in the circle to the right. The dot represents the center of the circle.
MrMuchimi

9514 1404 393

Answer:

  a = 57.5

  b = 90

  c = 65

Step-by-step explanation:

The measure of an inscribed angle is half that of the arc it intercepts. The angle at 'a' intercepts an arc of 115°, so its measure is (115/2)° = 57.5°

__

The inscribed angle at 'b' is a semicircle, 180°, so the measure of 'b' is (180/2)° = 90°.

__

The arc 'c' is the remainder of a semicircle after 115° have been taken away. Its measure is 180° -115° = 65°.

  (a, b, c) = (57.5, 90, 65)
