Answer: 5
Step-by-step explanation:
Answer:
y ≈ 61
Step-by-step explanation:
Using the Sine rule in the triangle
= ( cross- multiply )
y × sin18° = 21 × sin117° ( divide both sides by sin18° )
y = ≈ 61 ( to the nearest whole number )
Answer:
24
Step-by-step explanation:
It is done by Middle term splitting.
Taking the general equation ax² + bx + c, by middle term splitting, "b" should be splitted such that the numbers either on adding or on subtracting must be equal to "b" and their products must be equal to "a x c".
For example, in the question it's already given that the equation 8x² + bx + c is middle term splitted into 8x² + px + qx + 3.
So, that means "p x q" must be equal to "8 x 3", i.e., 24.
