First you would add the two angles together to get 105. The. you do 180-105 to get 75. That is the missing angle. From there you would correspond the angles with the sides. Therefore the answer is Angle AB, angle BC, angle CA. these are in order from shortest to longest

Answer:

AB, BC, AC

Step-by-step explanation:

Hi there,

In order to solve this problem, we should know that the longest side of the triangle is always opposite of the largest angle in a triangle. The first step is to find the angle measures. We are given the measures of ∠A and ∠C.

To find m∠B, just subtract the sum of the other angles and subtract the value from 180.

m∠A + m∠C + m∠B = 180°

65° + 40° + m∠B = 180°

105° + m∠B = 180°

m∠B = 75°

Now that we know all of the angle measures, we can identify the the lengths of the sides from least to greatest by looking at the angle value. <u>The greater the angle measure, the longer the opposite side would be. </u>

m∠A = 65° ⇒ opposite of side BC = medium side

m∠B = 75° ⇒ opposite of side AC = longest side

m∠C = 40° ⇒ opposite of side AB = shortest side

Hope this explanation helps. Cheers.

S_A_V [24]

Answer:

n + d = 20....n = 20 - d

0.05n + 0.10d = 1.35

0.05(20 - d) + 0.10n = 1.35

1 - 0.05d + 0.10d = 1.35

-0.05d + 0.10d = 1.35 - 1

0.05d = 0.35

d = 0.35/0.05

d = 7 <==== 7 dimes

n + d = 20

n + 7 = 20

n = 20 - 7

n = 13 <=== 13 nickels

Carla packed this box with 1-centimeter cubes. What is the volume of
Tomtit [17]

well i cannot see the box... but I can tell you how to solve the exercise.

imagine the box has height H, width W and Length L

the volume of said box would be V = H*W*L

now imagine that Carla's box was similar to this one.

and she filled this box with 1 cm cubes, assuming the height to be 3 cm

v= (number of cubes height) *(number of cubes width) *(number of cubes length) = 3 * 3 * 5  cubic cm= 45 cubic cm
