U can find the unit rate by looking where is the point so in that pic the unit rate I see is: 3/5

Answer:

the unit rate is also known as the slope. to find it you need to calculate from one point to the other.

Step-by-step explanation:

in this case the slope is 2/3 because from the coordinate (1,0) and (3,4) you go up 2 units to the right and 3 units up.

you can write this in slope-intercept form

y=2/3x+1

2/3 being the slope and 1 being the y intercept

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

$A+61.1\°+90\°=180\°$

$A=28.9\°$

F
Triangle equals 180
42+42=84
What is 180-84
That would be the next angle
