Answer:

25) cos X = 12/37            cos X = 0.3243                         X = 71.08 degrees

26) tan C = 32/24            tan C = 1.3333                          C = 53.13 degrees

27) sin Z = 15/25              sin Z = 0.6                                   Z = 36.87 degrees

28) sin A = 32/40             sin A = 0.8                                 A = 53.13 degrees

29) sin Z = 40/50             sin Z = 0.8                                  Z = 53.13 degrees

Answer:

25) 0.3243

26) 1.3333

27) 0.6000

28) 0.8000

29) 0.8000

Step-by-step explanation:

sin = opp/hyp

cos = adj/hyp

tan = opp/adj

25) cos X = 12/37 = 0.324324324

26) tan C = 32/24 = 1.33333333

27) sin Z = 15/25 = 0.6

28) sin A = 32/40 = 0.8

29) sin Z = 40/50 = 0.8

The sum of the measures of angle M and angle R is 90°.
denis23 [38]

Answer:

x = 5

Step-by-step explanation:

We have: The sum of the measures of angle M and angle R is 90°

M + R = 90°    

M = (5x + 10)°

Plug M into (1)

the equation: (5x + 10)° + R = 90°   (2)

R=55° into (2)

(5x + 10)° + 55° = 90°

5x + 10 + 55 = 90

 5x + 65 = 90

5x = 25

x = 5

By looking at the calculation below, write down a multiplication fact using the same numbers.
IrinaVladis [17]

Answer:

98 x 3 = 294 or 3 x 98 = 294

Step-by-step explanation:

Since 294 divided by 3 is 98, that means 294 is 3 times 98. So, we can say:

3 x 98 = 294

We can also say that 98 x 3 = 294 since it doesn't matter in which order you multiply.

A particular convex pentagon has two congruent, acute angles. The measure of each of the other interior angles is equal to the s
NNADVOKAT [17]

1. First, you must apply the formula for calculate the sum of the interior angles of a regular polygon, which is shown below:


 (n-2) × 180°


 "n" is the number of sides of the polygon (n=5).


 2. Then, the sum of the interior angles of the pentagon, is:


 (5-2)x180°=540°


 3. The problem says that the measure of each of the other interior angles is equal to the sum of the measures of the two acute angles and now you know that the sum of all the angles is 540°, then, you have:


 α+α+2α+2α+2α=540°

 8α=540°

 α=540°/8

 α=67.5°


 4. Finally, the larger angle is:


 2α=2(67.5°)=135°


 5. Therefore, the answer is: 135°
