One angle of a triangle measures 10 degrees more than the second. The measure of the third angle is
ollegr [7]

Answer:first angle = 25 degrees

Second angle = 35 degrees

Third side = 120/degrees

Step-by-step explanation:

Let the size of the second angle be x degrees.

One angle of a triangle measures 10 degrees more than the second. This means that the size of the first angle is ( x+ 10 )degrees.

The measure of the third angle is

twice the sum of the measures of the first two angles. This means that

The third angle = 2( first angle + second angle). So the size of each angle is

First angle (x + 10) degrees

Second angle = x degrees

Third angle = 2(x + 10 + x) =

(4x + 20) degrees

Sum of angles in a triangle = 180

degrees. Therefore,

x + 10 + x + 4x + 20 = 180 degrees

6x + 30 = 180

6x = 180 - 30 = 150

x = 150/6 = 25 degrees

First angle = x + 10 = 25 +10 = 35

Third angle = 4x + 20 = 4 × 25 + 20

= 100+ 20 = 120 degrees

The cost of a banquet can be calculated using the function
kotykmax [81]

Answer:

3 people attended the banquet

Step-by-step explanation:

The function is given as:

b = 75 + 15n where

b represents the total = 122

n represents the number of people attending = ??

If the total cost of the banquet is 122, how many people attended the banquet?

Hence,

122 = 75 + 15n

122 - 75 = 15n

47 = 15n

Divide both sides by 15

n = 47/15

n = 3.1333333333

Approximately to the nearest whole number = 3

Therefore, 3 people attended the banquet.
