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°.

Write an expression equivalent to m + m + m + m that is a sum of two terms.

Answers

Answer:

5m

Step-by-step explanation:

add them and add 1

An expression equivalent to m + m + m + m as a sum of two terms is 4m.

What is Expression?

An expression is combination of variables, numbers and operators.

The given expression is:

m + m + m + m

Equivalent expressions are expressions that work the same even though they look different.

We can combine like terms to simplify the expression:

m + m = 2m

Now plug in the expression of m+m in the given expression.

So the expression becomes:

m + m + m + m = 2m + 2m

Now we have expressed the given expression as a sum of two terms, which are both 2m:

2m + 2m = 4m

Therefore, an expression equivalent to m + m + m + m as a sum of two terms is 4m.

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

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
