Check the picture below.

now, recall, both blades are congruent, thus a = b, so c² = a² + b² -> c² = b² + b².

Find the area of the figure. Sides meet at right angles. No links please.
ss7ja [257]

Answer:

40 ft²

Step-by-step explanation:

Divide the figure into 2 rectangles and find their areas.

The area of the smaller rectangle

= 3 × 4

= 12 ft²

The area of the larger rectangle

= (8-4) × 7

= 28 ft²

The area of the figure

= 12 + 28

= <u>40 ft²</u>

Help please im new and i need help

Answer:

  B) False

Step-by-step explanation:

Triangles are similar when their angles are the same measures. Because the angles sum to 180°, we only need to show that 2 angles of one triangle are equal to 2 angles of the other triangle.

All three of the angles of the first triangle are given: 20°, 40°, 120°.

One of the angles of the second triangle matches: 40°; but the other angle (80°) doesn't match either of 20° or 120°.

The angles aren't the same, so the triangles are not similar.

__

If we want to go to the trouble, we can figure the third angle of the second triangle. It is 180° -40° -80° = 60°.

Then the angles in the two triangles, listed smallest to largest, are ...

  20°, 40°, 120°

  40°, 60°, 80°

It is clear the angles of these triangles are not the same.
