Answer:
a = 138
Step-by-step explanation:
Notice that from the figure, we can see that ∠MOQ and ∠PON are vertical angles, which means that by definition, they're congruent in measure.
∠MOQ = ∠MOR + ∠ROQ = 90 + 48 = 138°
So, this means that ∠PON is also equal to 138, which means a = 138.
Thus, the answer is a = 138.

Hey there!
Let's make a system of equations using x and y to find the two numbers.X is smaller and y will be larger.
x+y=98
y-4x=18
Now, let's solve the bottom equation for y so we can use substitution.
y=18+4x
Now we plug this into the first equation.
x+18+4x=98
5x+18=98
5x=80
x=16
Now, we plug this into the first equation to find y.
y=82.
So, the larger number is 82 and the smaller number is 16.
I hope this helps! Have a great day!
Answer:
X=1 because 2+5=7 then X=1 cause 1*2=2

Answer:
91 feet or 51
Step-by-step explanation:
17x 3= 51
51 + 40(what she dug before)
or it's just 51
This is true. It is called the exterior angle theorem. An example would taking a right triangle. An outside angle of the right angle would also be 90, while the remaining two inside's sum would also be 90.
