Mathematics
1 answer:
ella [17]3 years ago
8 0

Answer:

20

Step-by-step explanation:

3x + x + 100 = 180 (sum of angles on a straight line)

4x = 180-100

4x=80

divide both sides by 4

x=20

an isosceles triangle is drawn with base angles 24 degrees and a base of 28 cm. Find the base angles of the isosceles triangle w
Fofino [41]

Answer:

Step-by-step explanation:

height = 14tan(24°)

area = 0.5(base)(height)

Find the angle that triples the height.

tanθ = 3×14tan(24°)

θ = arctan(3×14tan(24°)) ≅ 53.2°

An angle measures 138° less than the measure of its supplementary angle. What is the
iren2701 [21]

The measure of each angle is 159° and 21°.

<h3>What are supplementary angles?</h3>
  • When two straight lines or rays intersect at a single endpoint, an angle is created.
  • The vertex of an angle is the location where two points come together.
  • The Latin word "angulus," which means "corner," is where the word "angle" originates.
  • Two angles are considered to be supplementary if their sums total 180 degrees.
  • For instance, angle 130° and angle 50° are complementary angles since the sum of these two angles is 180°.

So, supplementary angles = 180

Then,

  • 2x + 138 = 180
  • 2x = 180 - 138
  • 2x = 42
  • x = 21
  • 21 + 138 = 159

Therefore, the measure of each angle is 159° and 21°.

Help (this for a friend)<br> a 62.1<br> b 117.4<br> c 122.1<br> d 164.5
kramer

Answer:

c. 122.1 cm

Step-by-step explanation:

so l * w + \frac{\pi r^2}{2}

since 6 cm is the diameter

6/2 = 3

the radius (or r) is 3

so 18 * 6 + \frac{3.14 * 3*3}{y}

108 + \frac{3.14*9}{y}

108 + \frac{28.26}{2}

108 + 14.13 = 122.13

simplified: 122.1 cm

hope this helps:)
