vodomira [7]3 years ago
4 0

Answer:

x=5 cm

Step-by-step explanation:

The two triangles are similar by AA~. So, x and 4cm are corresponding side lengths, just like 4cm and 32 cm are.

Therefore, you can set up the proportion

4/32 = x/40 and solve to get x = 5

slavikrds [6]

Answer:

10.9

Step-by-step explanation:

Pythagoras theorem- a² + b² = c²

Since this is a right angle with each side on the right angle's length given you can use pythagoras theorem.

7² + 8.44² = c²

= 49 + 70.56 = c²

= 119.56 = c²

∴ c = √119.56

The top of angies ladder is resting against the side of her house 22 feet above the ground.If the base of the ladder is 5 feet f
Andrews [41]

Answer:

Step-by-step explanation:

The attached diagram shows the triangle ABC formed by the ladder with the wall of the house.

Triangle ABC is a right angle triangle. It has a 90 degree angle. The length of the ladder forms the hypotenuse(AC)of the triangle. This length can be determined by applying Pythagoras theorem

Hypotenuse^2 = opposite ^2 + adjacent^2

AC^2 = 22^2 + 5^2

AC^2 = 484 + 25 = 509

AC = √509

AC = 22.56

The slope of the ladder is

(change in y)/(change in x)

Slope = 22/5 = 4.4

Novosadov [1.4K]

For this case we have the following conversion of units:

1mi = 1609m

1h = 3600s

Thus, applying the conversion of units we have:

(23.35 \frac{mi}{h}) (\frac{1609}{1}\frac{m}{mi}) (\frac {1}{3600}\frac{h}{s}) = 10.4 \frac{m}{s}

Then, the distance traveled for 5 seconds is given by:

d = (10.4) (5)

d = 52m

Answer:

he has completed 52 meters of the 80-meter race
