Answer:
x = -√3 /2
y = ½
Step-by-step explanation:
x = cos 150°= -√3 /2
y = sin 150° = ½
Answer:
x = 10
Step-by-step explanation:
Since the triangles are similar the ratios of corresponding sides are equal
= , that is
= ( cross- multiply )
20(4x + 2) = 84x
80x + 40 = 84x ( subtract 80x from both sides )
40 = 4x ( divide both sides by 4 )
x = 10
The width of the rectangle is 16cm. this is because 16x4 = 64. so the height of the rectangle is 64 cm and 16cmx64cm = 1024cm squared. which is why the width of the rectangle is 16cm.
(0,1) is the y intercept because the point (0,1) lies on the y axis.
