Answer: x=29

Step-by-step explanation:

In a triangle, the sum of the measures of all angles is 180 degrees.

Therefore, we can add up all the angles in this triangle, setting them equal to 180:

65+57+2x=180

Using the equation above, solve for x:

Simplify:

122+2x=180

Subtract 122 from both sides:

(122+2x)-122=180-122

Simplify:

2x=58

Divide both sides by 2:

2x/2=58/2

Simplify:

x=29

Paladinen [302]

Answer:

B

Step-by-step explanation:

3x-7 <-4

Firstly solve this.

+7 +7

3x<3

÷3 ÷3

x<1

And because the inequality symbol isn't "equal to", the circle isn't coloured in.

The line will go from 1 to behind 0

Regular quadrilateral pyramid with base edge b=55 mm and lateral edge l = 7cm. Find the sum of all edges
egoroff_w [7]

Answer:

50cm or 500mm

Step-by-step explanation:

There are 4 base edges and 4 lateral edges, therefore, multiply the number for both edges by 4 and add.

Considering the fact that we were given two units of measurement, millimeters and centimeters, but we know that there are 10mm (millimeters) in a cm (centimeter) , we can just divide 55 by 10 to get 5.5.

¦

Therefore;

5.5 x 4 = 22

7 x 4 = 28

28 + 22 = 50cm

The diagram can be drawn in order to assist in answering the question.
