Answer:
Jamie is currently 15.
Step-by-step explanation:
3/8 = 0.375
40/0.375 = 106 and 2/3
Begin by using the cosine rule to find the unknown side.
Where a- unknown side, b is 12, c is 16 and angle in between is 108°
The cosine rule...
a² = b² + c² - 2bc cosA
= 12² + 16² - (2×12×16 cos108°)
= 518.655076
Taking the positive
square root...
a = 22.774
a = 22.8 cm nearest tenth
Answer:30
Step-by-step explanation:6 times 4 is24 and to the nearest 100 it will be 30
The matrix represents
-3x + 5y = 15
2x + 3y = -10
