In a triangle, the measure of one angle is five more than the first and the third angle is one more than four times the first.
katrin [286]

Answer:

A= 29

B=34

C=117

Step-by-step explanation:

<u>A triangle has three sides and a triangle always adds up to be 180</u>

A + B + C = 180

B = A + 5

C = 4A + 1

Plug in.

A + A + 5 + 4A + 1 = 180

6A + 6 = 180

6A = 174

A = 29

<u>Now since you found A, find the other two by plugging A in!</u>

C = 4(29) + 1

C = 117

<u>Plug in the B equation</u>

B = 29 + 5

B=34

Check your answers

29 + 117 + 34 = 180

Explain how similar objects and proportions are related. It's talking about polygons in geometry
malfutka [58]

Related sides the the same ratio so if I have a square with side length 10 and a similar one with side length of 5 the ratio is 1/2 when going from big to small or 2/1 when going small to big.  This is true for all sides.  This allows you to find missing sides using proportions.

The quotient of a number t and 4.2 is at most 15.​
frosja888 [35]

Answer:

t \leq 63

Step-by-step explanation:

Quotient of two numbers also means the result of the two numbers after division.

If the quotient of a number t and 4.2 is at most 15., this can be expressed using the inequality;

\dfrac{t}{4.2}\leq  15 <em>(note that at most 15 means that the highest value we can have is 15 after taking the quotient of the number hence the reason of the inequality sign.)</em>

<em></em>

On solving the inequality for the variable t

\dfrac{t}{4.2}\leq  15\\\\multiply \ both \ sides \ by \ 4.2\\\\\dfrac{t}{4.2}* 4.2\leq  15 * 4.2\\\\t \leq 63

<em>Hence t is at most 63</em>
