Find h step by step
miskamm [114]

Answer:

h = 2.7 m

Step-by-step explanation:

ΔADE and ΔABC are similar, hence ratios of corresponding sides are equal

DE / BC = AD / AB, that is

h / 0.9 = 18 / 6 ( cross- multiply )

6h = 16.2 ( divide both sides by 6 )

h = 2.7

spin [16.1K]

Answer:

7x - 2

Step-by-step explanation:

let x be the number of bags of chips, then

3x is the number of bags of pretzels ← 3 times the number of bags of chips

3x - 2 is the number of bags of nachos ← 2 less than bags of pretzels

total snacks bought = x + 3x + 3x - 2 = 7x - 2

I don't understand this question, picture attached.
mina [271]

We can find this using the formula for arc length (where r is the radius of the circle and \theta is the central angle in radians):

\textrm{Arc Length} = r\theta


In our problem, we are given 12 = 8\theta. This means that:

\theta = \dfrac{12}{8} = \boxed{\frac{3}{2}}


The measure of the angle is 1.5.
