What’s the measure of X in this short answers are fine
miv72 [106K]

Answer:

28 = x

Step-by-step explanation:

62 =  angle BAC  since they are vertical angles

angle ABC is a right angle since KL is perpendicular to FG

Adding the angles in triangle ABC

BAC + ABC + BCA = 180

62 + 90 + BCA = 180

152 + BCA = 180

BCA = 180-152

BCA = 28

BCA = x since they are vertical angles

28 = x

The length of a rectangle is 4 centimeters more than twice its width of the perimeter of the rectangle is 86centimeters find the
lana66690 [7]

Answer:

Width= 13 cm

length=30cm

Step-by-step explanation:

Let the length of the rectangle be 'L'

And the width of the rectangle be 'W'

Perimeter= 86 cm

According to the statement:

        Length= 2*Width+4\\L=2W+4

Perimeter of a rectangle= 2(Length+Width)

86=2(2W+4+W)\\86/2=3W+4\\43=3W+4\\3W=43-4\\3W=39\\W=39/3\\W=13 cm\\\\Length(L)=2W+4\\=2(13)+4=26+4=30 cm\\Length=30 cm

                               Width= 13 cm

                                length=30cm

Determine the measure of the missing angle in each triangle? <br> Please help me ASAP
IrinaK [193]

Answer:


Step-by-step explanation:

Sum of angles in a triangle = 180

1. 180 = 78 + 37 + x

180 = 115 + x

Subtract 115 from both sides

180 - 115 = 115 + x - 115

180 - 115 = x

65 = x

x = 65°


2. 180 = 80 + 66 + x

180 = 146 + x

Subtract 146 from both sides

180 - 146 = 146 + x - 146

34 = x

x = 34°
