Answer:
15°
Step-by-step explanation:
We know sum of 3 angles is a triangle is always 180°.
Since, this is a right triangle, ONE ANGLE IS 90°. THus, the other two must sum 90.
Let one of the acute angles be x
Since the other is 5 times this, that one is 5x
Thus, now we can write:
x + 5x = 90
Solving for x:
Since x = 15, "5x" would be 5 * 15 = 75
THus, one acute angle is 15 and another is 75, so the smallest is 15

Answer:
Irrational.
Step-by-step explanation:
√15 is irrational because although it can be written as a decimal, it cannot be written as a fraction, which is one of the main factors that defines what makes an irrational number.
Answer:
25%
Step-by-step explanation:
Step 1: Add all the possible choices up
8 + 5 + 7 = 20
Step 2: Note that your finding the probability for creme filled ones
Step 3: Make it a fraction
5 creme filles ones out of 20
5/20
Step 4: Simplify
1/4
Step 5: Convert into a decimal (if you don't already know it)
1 ÷ 4 =
.25
Step 6: Multiply by 100 to find percentage
.25 × 100 = 25%
(x-10)+(x+2)=90
2x-8=90
2x=98
x=49
angle E is 39 and angle F is 52
