Answer:
4
Step-by-step explanation:
I think you just need to flip the number to get it so it goues as 4/1 and if 4 divided by 1 is 4
Answer:
c = 30
Step-by-step explanation:
Given:
a + b = 150
As the triangle is a right angled triangle,
a + 90 = 150
a = 60
Hence, from angle sum property,
a + b + c = 180
150 + c = 180
c = 30
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
<span>d. for a right triangle, if a, b, and c are the sides of the triangle with c being the hypotenuse, then a^2+b^2+c^2</span>
