Answer:

You could only draw one triangle because the other side of the triangle can only be one value. This is because when the angle measure between two sides and the length of the sides is given, the length of the other side is fixed. This is also modeled by the SAS principle of congruence.

Is this a right triangle? 15 m, 36 m, 39 m

Vesnalui [34]

Answer:

YES

Step-by-step explanation:

use pythagorean theorem

15^2 + 36^2 = 39^2

225 + 1296 = 1521

Alison is learning how to walk. 50% of the time that she takes a step she falls down. Her older brother wants to design a simula

MissTica

Answer with explanation:

Alison is learning how to walk.50% of times she takes a step she falls down.

Probability of falling down in next step $=\frac{50}{100}=\frac{1}{2}$

Probability of not falling down in next step $=\frac{50}{100}=\frac{1}{2}$

From ,the four option given,we have to find the best simulation which her older brother wants to design a simulation to find the probability that she will fall down 5 out of the next 7 times she tries to take step.

While Simulating the Probability of falling down should be $=\frac{5}{7}$

And , probability of not falling down $1-\frac{5}{7}=\frac{2}{7}$

→→⇒F=Falling, NF=Non Falling

A) Roll a die letting 1 represent Alison falling and 2-6 represent Alison not falling. Roll the die five times.

$P(F)=\frac{1}{6},P(NF)=\frac{5}{6}$

Incorrect option,probabilities of falling and non falling does not match with Actual probability of falling and non falling.

B) Roll a die letting 1 represent Alison falling and 2-6 represent Alison not falling. Roll the die seven times.

$P(F)=\frac{1}{6},P(NF)=\frac{5}{6}$

Incorrect option,probabilities of falling and non falling does not match with Actual probability of falling and non falling.

C) Let Heads represent Alison falling down and Tails representing Alison not falling down. Flip the coin five times.

$P(F)=\frac{1}{2},P(NF)=\frac{1}{2}$

Simulation is done only five times , that is coin has been flipped only five times.it must have been flipped seven times.Incorrect option.

D) Let Heads represent Alison falling down and Tails representing Alison not falling down. Flip the coin seven times.

$P(F)=\frac{1}{2},P(NF)=\frac{1}{2}$

Simulation is done seven times , that is coin has been flipped seven times.So,she should fall 5 times that is head should appear 5 out of seven times, and tail should appear 2 out of seven times.correct option.

The two men measure the angle of elevation to the highest point on the rock to be 22.6°. They

IgorC [24]

Answer:

15 m

Step-by-step explanation:

Refer to attached picture

The height = h
Angles of elevation 22.6° and 38.3°
Closer distance = d

Use tangent to solve

tan 22.6° = h/(d + 17) ⇒ h = (d + 17) tan 22.6° ⇒ h = 0.42(d + 17)
tan 38.3° = h/d ⇒ h = d tan 38.3° ⇒ h = 0.79d

Compare the equations above and find the value of d:

0.42(d + 17) = 0.79d
0.42d + 7.14 = 0.79d
0.79d - 0.42d = 7.14
0.37 d = 7.14
d = 7.14/0.37
d = 19.3 m

Now find the value of h:

h = 0.79d
h = 0.79*19.3
h = 15
