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 )
8 units to the left and 5 units up.
Just pick any point on the blue triangle and count how many you move to get to that same point on the red triangle.
Answer:
x =2
Step-by-step explanation:
(x+4) /3 = 2
Multiply each side by 3
(x+4) /3 *3= 2*3
x+4 = 6
Subtract 4
x+4-4 = 6-4
x =2
Answer:
$180
Step-by-step explanation:
25% ->0.25
144(0.25)=36
36+144=180
30+5y_>4x
5y_>4x-30
The answer is: y_>(4/5)x-6
