If each quadrilateral below is a trapezoid, find the missing measures.
#1

Answers

Answer:

C = 101

E = 46

Step-by-step explanation:

79 + 134 = 213

180 - 79 = 101 (C+F has to equal 180)

79 + 134 + 101 = 314

360 - 314 = 49 (trapezoids have a total degree of 360)

The measure of angles are ∠C = 101°, ∠E = 46°, ∠J = 83°, ∠L =97°, and ∠M = 97°.

It is given in the picture that measures the angles of a trapezoid.

It is required to find the other angles.

What is a trapezoid?

It is defined as the quadrilateral having four sides in which two sides are parallel to each other it is a 2-dimensional geometry.

We have a trapezoid CDEF in which ∠D = 134° and ∠CFE = 79°

We know in trapezoid:

∠C+∠F = 180° and

∠D+∠E = 180°

For ∠C = 180° - ∠F ⇒ 180° - 79° ⇒ 101°

For ∠E = 180° - ∠E  ⇒ 180° - 134° ⇒46°

We have another trapezoid JKLM in which ∠K = 83°

We know in isosceles trpezoid:

∠K = ∠J = 83° and

∠L = ∠M

∠L = 180° - ∠K ⇒ 180° - 83°  ⇒ 97° ⇒ ∠M

Thus, the measure of angles are ∠C = 101°, ∠E = 46°, ∠J = 83°, ∠L =97°, and ∠M = 97°.

1. a circle has a circumfrance 88cm find its radius
2.a sector with angle 45 degrees has ab arc length 44cm find it radius and perimeter speratly
pls answer asap i will give u the brainliest

Answers

Step-by-step explanation:

Number 1

Circumference = 88cm

Circumference = 2πr

2πr = 88

πr = 88/2

πr = 44

22r/7 = 44

22r = (44 × 7)

r = (44 × 7)/22

r = 2 × 7

r = 14cm

Number 2

Length of arc = 44cm

Angle = 45°

L = ∅/360 × 2πr

44 = 45/360 × 2πr

44 = ⅛ × 2πr

44 = ¼ × πr

πr = 44 × 4

22r/7 = (44 × 4)

22r = (44 × 4 × 7)

r = (44 × 4 × 7)/22

r = 2 × 4 × 7

r = 2 × 28

r = 56cm

Perimeter = L + 2r

P = 44cm + 2(56cm)

P = 44cm + 112cm

P = 156cm

Answers

Answer:

y=9x

Step-by-step explanation:

First let's find the slope of this.

To find the slop we can take two points.

(1,9) & (3,27)

27-9/ 3-1 (slope equation) = 18/2=9

The slope of the equation is 9.

Now let's use point-slope form to find the equation.

(1,9)

y-9=m(x-1) (substitute the x2 and y2 values for the coordinate values)

y-9=9(x-1) (substitute m for the slope)

y=9x-9+9

y=9x

Which answer is correct?

9= 4 + 5 and 9 = 2 +7
9 = 5 + 5 and 9 = 6 + 4
9=6+3 and 9 = 7+1
9 = 5 + 3 and 9 = 6 +2

Step-by-step explanation:

The sign shows that any number that is equal to, or more than, 36 is a valid answer. It can't be 3 because 3 x 9 is 27, and 27 is less than 36, so that wouldn't be true. 4 x 9 is 36, and 36 = 36, so that would be true, and obvoiusly all the other numbers that are over 4, when multiplied by 9, will equal more than 36, so they are all correct, except for the 3 and none answers.
