Hello!
To find this you have to divide the total number of hours studied by the time spent studying social studies
This can be done by does 4 * 0.25 = 1
The answer is 1 hour
Hope this helps!
Answer:
15
Step-by-step explanation:
A right angle is 90 degrees
The given angle is 75
90 + x + 75 = 180 (all three angles always add to 180 degrees)
165 + x = 180
180-165 = 15
Answer:
The answer is 72.
Step-by-step explanation:
Hope this helps you out!
I showed my work in the photo.
Answer:

Step-by-step explanation:
Two ∆s can be considered to be congruent to each other using the Side-Angle-Side Congruence Theorem, if an included angle, and two sides of a ∆ are congruent to an included angle and two corresponding sides of another ∆.
∆ABC and ∆DEF has been drawn as shown in the attachment below.
We are given that
and also
.
In order to prove that ∆ABC
∆DEF using the Side-Angle-Side Congruence Theorem, an included angle which lies between two known side must be made know in each given ∆s, which must be congruent accordingly to each other.
The included angle has been shown in the ∆s drawn in the diagram attached below.
Therefore, the additional information that would be need is:
