Answer:
Step-by-step explanation:
Let tacos be x and burritos be y
So, Avery purchased 4x+2y = 21
Sasha purchased 4x+3y = 26.5
Solving the 2 eqns:
4x+2y=21
-4x-3y=-26.5
-y=-5.5
The cost of one burrito is $5.5
Answer:

Step-by-step explanation:
see the attached figure with letters to better understand the problem
step 1
Find the measure of angle ABC
we know that
----> by alternate interior angles
step 2
Find the measure of angle x
we know that
The <u><em>Exterior Angle Theorem</em></u> states that The exterior angle of a triangle is equal to the sum of the two opposite interior angles
so
In the triangle ABC

we have

substitute

Step-by-step explanation:
first we use Pythagoras to get t :
c² = a² + b²
with c being the Hypotenuse.
so,
t² = r² + s² = 10² + 31² = 100 + 961 = 1061
t = sqrt(1061)
and then we use the law of sine :
a/sin(A) = b/sin(B) = c/sin(C)
with the angles being opposite of their related sides.
so, r/sin(R) = t/sin(T) = t/sin(90) = t/1 = t
sin(R) = r/t = 10/sqrt(1061) = 0.30700278...
R = 17.8786966... ≈ 17.9°
