Answer:

x = 31°

Step-by-step explanation:

\triangle ABC \cong \triangle DCE... (given) \\\\\therefore m\angle B = m\angle E..(cact)\\\\\because m\angle B = 61\degree \\\\\therefore m\angle E = 61\degree \\\\In \: \triangle DCE\\\\m\angle D+ m\angle C + m\angle E = 180\degree \\(by \:  interior \:  angle  \: sum \:  property \:  of \:  a triangle) \\\\2x\degree + 57\degree + 61\degree= 180\degree \\\\2x\degree + 118\degree = 180\degree \\\\2x\degree = 180\degree - 118\degree  \\\\2x\degree = 62\degree  \\\\x = \frac{62\degree}{2} \\\\x = 31\degree

♡ The Explanation/Step-By-Step ♡

- 6/100 + 5/100 + 80/100 + 9/100

Apply the fraction rule! --> a/c + b/c = a + b over c

6/100 + 5/100 + 80/100 + 9/100 = 6 + 5 + 80 + 9 over 100

Add the numbers: 6 + 5 + 80 + 9 = 100!

= 100/100 Apply the fraction rule! a/a = 1

a/a = 1 = 100/100 = 1

A circle has a central angle measuring StartFraction 7 pi Over 10 EndFraction radians that intersects an arc of length 33 cm. Wh
cupoosta [38]

The radius of the given circle with a central angle of 7π/10 and arc length of 33cm is 15cm.

It is given that

The central angle of the given circle = 7π/10 radians

Length of arc = 33cm

<h3>What is the formula for arc length?</h3>

Arc length = central angle* radius

From the above formula

Radius = Arc length/Central Angle

Radius = \frac{33}{(7\pi)/10 }

Radius = 15cm

Therefore, radius of the given circle is 15cm.
