Answer:
96 degrees
Step-by-step explanation:
The 144 degrees is on a straight line, meaning the angle next to it inside the triangle and 144 are supplementary. They add up to 180 degrees.
Coincidentally, the other two angles plus the third, unlabeled angle will add up to 180 degrees as well, meaning that the the 48+x = 144 degrees (according the property of equality, which is if a=b and b=c, then a=c). Solve for x from there:
x = 144-48
x = 96
First let establish the eqautionlet y be the total costx is the number of orders
y = 3x + 115
since the minimum order is 25x >= 25
then The school can spend a maximum of $800
800 <= 3x + 115
800 - 115 <= 3x685 <= 3x685/3 <= x228.33 <= x

SSS congruence rule.
Solution:
Given ΔABC and ΔDEF are congruent.
To prove that on which rule they are congruence.
In triangle ABC,
AB = 2.5 cm, BC = 1.8 cm, CA = 1.8 cm
In triangle DEF,
DE = 2.5 cm, EF = 1.8 cm, FD = 1.8 cm
Consider ΔABC and ΔDEF,
AB = DE (Side)
BC = EF (Side)
CA = FD (Side)
∴ ΔABC ≅ ΔDEF (by SSS congruence rule)
Hence, the given triangles are congruent by SSS congruence rule.
