Answer:</h2>

<h2>
Step-by-step explanation:</h2>
For a better understanding of this problem, see the figure below. Our goal is to find
. Since:

and
is a common side both for ΔMRN and ΔMQN, then by SAS postulate, these two triangles are congruent and:

By Pythagorean theorem, for triangle NQP:

Applying Pythagorean theorem again, but for triangle MQN:

Answer:
54
Step-by-step explanation:

Parentheses (14 + 42 - 6) = 50:
⇒ 50/10 + 7²
Exponents 7² = 49:
⇒ 50/10 + 49
Multiplication/division 50/10 = 5:
⇒ 5 + 49
Addition/subtraction: 5 + 49 = 54
⇒ 54
Answer:
Step-by-step explanation:
if you're saying she ran .2 miles in 12 hours
then she ran .016 miles per hour
if you're saying she ran 2 miles in 12 hours,
then she ran 1/3 mile per hour or 0.3333 miles per hour
Reciprocal means invert it . for eg- the reciprocal of 1/2 is 2/1 and of 4/7 is7/4.
