180-45=135 
135/2=67.5 for the other two angles

Answer:

67.5 degrees.

Step-by-step explanation:

Let the measure of two equal angles of the triangles is x.

Thus, the angles of the triangles are x, x and 45 degrees.

The sum of the measures of the angles of all triangles is 180 degrees.

Hence, the equation is

x + x + 45 = 180

Solve the equation for x

2x + 45 = 180

2x = 180 - 45

2x = 135

x = 67.5

Therefore, measure of other two angles are 67.5 degrees.

The sum of three numbers is 72
LekaFEV [45]

Answer: <u><em>The first number is 8</em></u>

Step-by-step explanation: Let the three No. s be x, y and z respectively

given = x+ y+ z= 72

y=7x

z=7x-18

∴As we know x+ y+ z=72

i.e. x+7x+7x-18=72

15x=72+18=90

15x=90

x=90/15

∴x=8

∴y=7x

7×8=56

∴z=7x-18

56-18=38

∴<u><em>The first no. is x=8</em></u>

<u><em>The second no. is y=7x = 56</em></u>

<u><em>The third no. is z=7x-18 = 38</em></u>

Find c and round to the nearest tenth
Makovka662 [10]

Answer:

Step-by-step explanation:

<C = ?

a = 22

b = 20

c = 18

Formula

c^2 = a^2 + b^2 - 2*a*b* cos(C)

Solution

18^2 = 22^2 + 20^2 - 2*22*20*cos(C)

324 = 484 + 400 - 880*cos(C)

324 = 884 - 880*Cos(C)

-560 = - 880 * cos(C)              

-560 / - 880 = cos(C)

0.63636   =  cos(C)

C = cos-1(0.63636)

C =50.48
