1. Convert 60° to radians.
hram777 [196]

Answer:

60° = \frac{\pi }{3} radians

Step-by-step explanation:

To convert from degrees to radians

radian measure = degree measure × \frac{\pi }{180}

Thus 60° in radian measure

= 60 × \frac{\pi }{180} ( divide ( cancel) 60 and 180 by 60 )

= \frac{\pi }{3}

Solve 2x2 + 5x = 12
Delvig [45]

Answer:

A

Step-by-step explanation:

2x² + 5x = 12

2x² + 5x - 12 = 0

x² + 5x - 24 = 0

factors of 24 are 1, 2, 3, 4, 6, 8, 12, 24. the only pair that adds to 5 is 8 and 3

2x² - 3x + 8x - 12 = 0

split the equation and factor

2x² - 3x = 0 ||| 8x - 12 = 0

x(2x - 3) ||| 4(2x - 3)

therefore the pair is (2x - 3)(x + 4)

2x - 3 = 0

2x = 3

x = 3/2

or

x + 4 = 0

x = -4

10. If possible, determine whether or not triangles LQP and LMN
natita [175]

Answer:

They are similar

Step-by-step explanation:

If two triangles are similar, the ratio of their corresponding side lengths must be equal to each other.

This means that for ∆LQP and ∆LMN to be considered similar to each other, therefore:

LM/LQ = LN/LP

LM = 100

LQ = 12

LN = 75

LP = 9

LM/LQ = 100/12 = 25/3

LN/LP = 75/9 = 25/3

LM/LQ = LN/LP = 25/3, therefore ∆LQP and ∆LMN are similar to each other because the ratio of their corresponding side lengths are the same.
