Solve the right triangle, ΔABC, for all the missing side and angles to the nearest tenth given sides a = 10.6 and b = 19.2.

Aliun [14]

Answer:

Part 1) $c=21.9\ units$

Part 2) $B=61.1\°$

Part 3) $A=28.9\°$

Part 4) $C=90\°$

Step-by-step explanation:

step 1

Find the length side c

Applying the Pythagoras Theorem

$c^{2}=a^{2}+b^{2}$

substitute the given values

$c^{2}=10.6^{2}+19.2^{2}$

$c^{2}=481$

$c=21.9\ units$

step 2

Fin the measure of angle B

we know that

In the right triangle

$tan(B)=b/a$

substitute the given values

$tan(B)=19.2/10.6$

$B=arctan(19.2/10.6)=61.1\°$

step 3

Find the measure of angle A

we know that

The measure of interior angles in a triangle must be equal to 180 degrees

∠A+∠B+∠C=180°

Remember that in a right triangle the measure of angle C is 90 degrees

we have

$B=61.1\°$

$C=90\°$

substitute

$A+61.1\°+90\°=180\°$

$A=28.9\°$

Equation for y and what if equals too

katen-ka-za [31]

The answer is y = 35x + 20.

In order to find this, start with two ordered pairs. For the purpose of this problem, we'll use (1, 55) and (2, 90). Now we use the slope formula to find the value next to x in the equation.

m(slope) = (y2 - y1)/(x2-x1)

In this equation (x1, y1) is the first ordered pair and (x2, y2) is the second. Plug in to the equation and solve.

m = (90 - 55)/(2 - 1)

m = 35/1

m = 35

Now that we have the slope, plug that into the equation along with either point to find the intercept (the last number).

y = mx + b

55 = 35(1) + b

55 = 35 + b

20 = b

Now that we have the slope and intercept, we can use each to fill in those blanks.

y = 35x + 20

A model car has a scale factor of 1 64 164 The diameter of a tire on the model is 0.41 inches. So, the diameter of the tire on a

Alchen [17]

Answer: 26.24 inches

Step-to-step explanation:

Given:

The scale factor to model car= $\frac{1}{64}\ inches$

Thus, if diameter of tire of the actual car is k then diameter of model car = $\frac{1}{64}k$

Since, the diameter of tire of the model car= 0.41 inches

$\\\Rightarrow\frac{1}{64}k=0.41\\\Rightarrow\ k=0.41\times64\\\Rightarrow\ k=26.24\ inches$

hence, the diameter of tire of the actual car= 26.24 inches
