Answer is A, Three months, 1/4
A. 13
Step-by-step explanation:
What we are given....
∠A = 26° + x
∠B = 38° + x
∠A and ∠B are complementary
If complementary angles add up to equal 90° and ∠A and ∠B are complementary to each other
Then 26 + x + 38 + x = 90
^ ( Note that we just created an equation that we can use to solve for x )
Now its just basic algebra
26 + x + 38 + x = 90
step 1 combine like terms
26 + 38 = 64
x + x = 2x
we now have 64 + 2x = 90
step 2 subtract 64 from each side
64 - 64 cancels out
90 - 64 = 26
we now have 26 = 2x
step 3 divide each side by 2
26 / 2 = 13
2x / 2 = x
we're left with x = 13
Answer:
Step-by-step explanation:
Given:
For Δ ABC
m∠A=°
m∠B=°
m∠C=°
To find value of .
Solution:
For all triangles the sum of all 3 angles = 180°
Thus, we have:
Plugging the values in degrees.
Combining like terms.
Subtracting both sides by 6.
Dividing both sides by 6.
∴ (Answer)
In an hour, she can write 3,750 words and in one minute she can write 62.5
22,500/5 = 3,750
3,750/60 = 62.5
