Answer:

Step-by-step explanation:

Let the third angle be x

Sum of all the angles of a triangle = 180°

25 + 40 + x = 180

65 + x = 180

x = 180 - 65

x = 115°

Answer:

115 degrees

Step-by-step explanation:

for all triangles, the sum of all their angles is 180 degrees so...

180-40-25=115

so the third angle is 115

In the figure shown, r || s. If the measure of ∠ 2 = 146°, what is the measure of ∠ 7
borishaifa [10]

Answer:

34°

Step-by-step explanation:

1. First, let's find the measure of ∠1 because since r || s, that means ∠1 = ∠7 because they're both alternate exterior angles. Alternate exterior angles are congruent.

2. (Solving for ∠1)

  • 146 + x = 180
  • 146 + x - 146 = 180 - 146
  • x = 34

3. Now, since we know ∠1 = ∠7, ∠7 = 34°.

Answer:

6

Step-by-step explanation:

10/5 ×/3 multiply 10×3 and than divide by 5

or another way start with multiplying 5 and n equaling 5n=

than 10× 3= 30 so you're left with 5n=30 divied 30 by 5 equalling 6

so x=6

Select the correct answer.
Musya8 [376]

Answer:

Before Tim ate any of the jellybeans, here are numbers: 

pineapple or p  =10

raspberry or  r = 10

orange or o = 10

 

Tim has eaten 6 orange and 4 pineapple jellybeans. Hence, what's left are: 

 p = 10-4 =6

o = 10-6 =4

r = 10 so now total jelly beans are 20

So the probability of getting a raspberry is: 

p(r) = number of r/total

10/20 or 50%
