Answer:

No triangles are possible.

Step-by-step explanation:

<u>Given</u>:

m∠A = 18°
side c = 19 in
side a = 4 in

In a triangle ABC:

A, B and C are the interior angles.
a, b and c are the sides opposite the corresponding interior angles.

The interior angles of a triangle <u>sum to 180°</u>.

Given m∠A = 18°, the sum of angles B and C is:

⇒ m∠B + m∠C = 180° - 18° = 162°

As there is no answer option where the sum of angles B and C equals 162°, no triangles are possible from the given answer options.

Jade can do 65 push ups in 5 minutes. At the same rate, how many push ups can you expect her to do in 7 minutes?

hram777 [196]

Answer:

Step-by-step explanation:

Set up a proportion, where x is the number of push ups she can do in 7 minutes

$\frac{65}{5}$ = $\frac{x}{7}$

Cross multiply and solve for x:

5x = 455

x = 91

So, Jade can do 91 push ups in 7 minutes

To the nearest tenth, which is the BEST estimate for the volume of the given pyramid?

mixer [17]

Answer:

4.2 cubic inches

Step-by-step explanation:

Find the diagram attached

Volume of the rectangular pyramid = BH/3

B is the base area

H is the height of the pyramid

Given

Base area = 3.2in * 1.4in

Base area = 4.48sq. in

Height = 2.8in

Volume of the rectangular pyramid = 4.48*2.8/3

Volume of the rectangular pyramid = 12.544/3

Volume of the rectangular pyramid = 4.2 cubic inches

A 10-foot ladder is leaning against a wall. The base of the ladder is 2 feet from the base of the building. How far up the build

Svetlanka [38]

We can see on this graph that the triangle has legs of x and 6 with a hypotenuse of 10 and we can use Pythagoreans theorem to find the unknown side.
Pythagoreans theorem: a^2+b^2=c^2, where a and b are the legs of the triangle and c, is the hypotenuse

x^2+6^2=10^2 Plugin a=x, b=6, and c=10. Now let us solve for x

x^2+36=100 Square each individual term

x^2+=100+36 Subtract 36 from both sides

x^2=64 Combine like terms

sqrt(2)=sqrt(64) Take the square root of both sides

x = 8 Simplify the square root

So our answer is x = 8
The ladder touches the 8 feet mark on the wall.
