So 3 times the measure of a small angle
3x + x= 180
4x = 180
X= 45
3(45) + 4(45) = 180
Hope this helps!
Answer:
$19.26 or $19.
Step-by-step explanation:
Sold DVD for 50% more of the purchase price of $12, so:

18 * (1.07) = $19.26
Answer:
31.7 cm²
Step-by-step explanation:
The area (A) of the triangle is calculated as
A =
absinC
where a, b are the 2 sides given and C the angle between them
∠ C = 180° - (72 + 59)° = 180° - 131° = 49° , thus
A = 0.5 × 12 × 7 × sin49° ≈ 31.7 cm² ( to 1 dec. place )
