The sum of the angles in a triangle is 180°, then:
68°+26°+x°=180°
Solve it as an equation:
68+26+x=180
x=180-68-26
x=86°

The figures are similar. Find the area.
Crazy boy [7]

Answer:

108 in

Step-by-step explanation:

The figures are similar, so if we find a relation of the area and the diagonal in rectangle 1  we can apply it to rectangle 2.

rectangle 1 :

72/x=12

x=6

therefore

72/6=12

rectangle 2:

A/x=18

A/6=18

6*18=108

A=108 in

Hope this helps

Find the lateral area of a cylinder with the given measurements. Use 3.14 for pi and round your answer to the nearest tenth.

height: 15 centimeters

radius: 9 centimeters

Question 11 options:

787.3 cm2

1356.5 cm2

847.8 cm2

889.9 cm2

So we know the formula for the lateral area of a cylinder is:

AL=2πrh

now all we have to do is put the given value in place of the correct variable then solve like so:

AL=2*3.14*9*15

AL= 847.8 cm2

so the answer is the third option

hope this helps
