Answer:

A) SAS

Step-by-step explanation:

The picture gives us that two sides are congruent. We can see that an <em>angle</em> is congruent as well because they share a common point at their tip.

If we look at just the area of intersection, it looks like an X. Think of the X as two lines intersecting. Each side equals 180°, and because both triangles are made up of those sides, we can conclude that the angles are congruent as well.

Hope this helps!

Jasmine thinks that the images are the same because they are both isosceles triangles. Do you agree with Jasmine why or why not?

lorasvet [3.4K]

Answer:

No, images are not same as their dimensions are different although two sides in each of the two triangles are equal.

Step-by-step explanation:

Given: images of two isosceles triangles.

To check: if images are the same

Solution:

A triangle is a polygon made up of three sides.

An isosceles triangle is a triangle in which two sides are equal. Also, in an isosceles triangle, angles opposite to equal sides are equal.

The given images of two isosceles triangles A and B are not the same as their dimensions are different although two sides in each of the two triangles are equal.

A scuba diver dove from the surface of the ocean to an elevation of -79 9/10 feet at a rate of -21.3 per minute. After spending

saw5 [17]

Answer:

The rate of change of the divers elevation is approximately 24.71 feet/minute

Step-by-step explanation:

The given information are;

The depth to which the scuba diver dove = $-79\frac{9}{10} \ feet$

The rate at which he dove = -21.3 feet/minute

The time which he spent at that elevation = 10.5 minutes

The elevation the diver then ascended to = $-8\frac{9}{10} \ feet$

The total time for the dive = $17\frac{1}{8} \ minutes$

Therefore, the time, $t_d$ , with which the scuba diver descended to $-79\frac{9}{10} \ feet$ is given as follows;

$t_d = \dfrac{Distance}{Speed} = \dfrac{-79\frac{9}{10} }{-21.3} \approx 3.75 \ minutes$

The time, $t_e$ , it took the scuba diver to elevate to $-8\frac{9}{10} \ feet$ is given as follows;

$t_e$ = $17\frac{1}{8} \ minutes$ - (3.75 + 10.5) minutes ≈ 2.8738 minutes

The rate of change of the divers elevation = (Final elevation - Initial elevation)/(Time taken)

∴ The rate of change of the divers elevation = ( $-8\frac{9}{10} \ feet$ - ( $-79\frac{9}{10} \ feet$ ))/(2.87 minutes) = 71/2.8738 ≈ 24.71 feet/minute to the nearest hundredth

The rate of change of the divers elevation ≈ 24.71 feet/minute.
