Alright, lets say the measure of the 3rd angle (the smallest one) is x degree, then measure of the 1st angle will be (x + 25) degree, and 2nd one: 3x degree. The sum of all the angles in any triangles is 180 degrees.

(x + 25) + 3x + x = 180

5x + 25 = 180 ---> 5x = 180 - 25 ---> 5x = 155 ---> x = 155/5 ---> x = 31o (third angle)

31 + 25 = 56o (first angle)

3 × 31 = 93o (second angle)

56 + 93 + 31 = 180

What is the answer and why is it that answer

Dmitry_Shevchenko [17]

Answer:

Step-by-step explanation:

73+107 = 180. When the smaller of the two angles is 73 all of the smaller angles are also going to be 73 and since the angles MTS and STN are bigger angles they both have to be 107

I’m confused with this math problem, look at the picture please

Softa [21]

A cube has six sides so i divide 150 by 6 which is 25, so now we know wach side has an area of 25 square inches, square root 25 is 5. now we know each side length is 5 inches

Mr. Lynch bought some oranges and pears.

Illusion [34]

Answer:

11: 12

Step-by-step explanation:

Let the number of oranges and pears Mr Lynch have initially be x and p respectively.

x -10= ½p

2(x -10)= p

p= 2x -20 -----(1)

Since Mr Lynch did not give any pears away, the number of pears at the end is the initial number of pears.

p= 24

Substitute p= 24 into (1):

2x -20= 24

2x= 24 +20 (+20 on both sides)

2x= 44

x= 44 ÷2

x= 22

$\frac{x}{p} = \frac{22}{24}$

$\frac{x}{p} = \frac{11}{12}$

Thus the ratio of orange to pears in the beginning is 11: 12.
