The diagram shows a parallelogram.

emmasim [6.3K]

Answer:

27.44 square cm

Step-by-step explanation:

If the length of parallelogram is a and b and angle between side a and b is $\alpha$ .

Then area of parallelogram = $a*b*sin(\alpha ) = ab sin(\alpha )$

Given side length 4 cm and 7 cm

angle between them = 100°

value of sin(100°) = 0.98

Thus, area of given parallelogram = 4*7*sin(100°) = 28*0.98 = 27.44

Thus, area of given parallelogram is 27.44 square cm.

What is the equation of the line with an x-intercept of -1 and a y-intercept of 2? y = 2x - 2 y = - 2x 2 y = 2x 2

guajiro [1.7K]

X intercept = -1, y = 0 (-1, 0)

<span>y intercept = 2, x = 0 (0, 2)
</span>
slope between (-1, 0) and (0, 2):

slope = (2 -0)/(0 - -1) = 2/1 = 2, m = 2

Using point (-1, 0) x₁ = -1, y₁ = 0

y - y₁ = m(x - x₁)

y - 0 = 2*(x - -1)

y = 2(x + 1)

y = 2x + 2

Players a, b, and c toss a fair coin in order. the first to throw a head wins. what are their respective chances of winning

Tatiana [17]

Probability a gets a head = 1/2
.. .. .. b .. .. ... .. = P(a gets tail) * 1/2 = 1/2 * 1/2 = 1/4
.. ... . .. c .. .. .. .. . = P(and and b gets tail) * 1/2 = 1/4 * 1/2 = 1/8
