Answer:

Square

Step-by-step explanation:

Given

\angle 1 = x + 60

\angle 2 = 2x + 30

1 and 2 are consecutive

Required

Determine a special name to the parallelogram

For consecutive angles 1 and 2 of a parallelogram, we have:

\angle 1 + \angle 2 = 180

x + 60 + 2x + 30 = 180

3x +90 = 180

Collect like terms

3x = 180 - 90

3x = 90

x = 30

Next, is to calculate angles 1 and 2

\angle 1 = x + 60

\angle = 30 + 60 = 90

\angle 2 = 2x + 30

\angle 2= 2*30 + 30 = 90

Both angles are 90.

This implies that each angle in the parallelogram is 90.

<em>Such a parallelogram is either a rectangle or a square</em>

qwelly [4]

Answer:

2

Step-by-step explanation:

Since the 3's are the same on either side, you need to find a number that, when multiplied by 9, yields 18. The only number that satisfies that is 2, which is the answer. Hope this helps!

Prove that: 16sin20.sin40.sin60.sin80=3​
olga nikolaevna [1]

to prove that 6720. Sin 40. Sin 60. 80 equals 3 you'd have to divide 16 by 20 multiply subtract both sides by 3 which is 24x + 6x + 8x + -14 equals 40 40 + 20 equals 16 - -40 equals 80 which equals to 3

A conical paper cup has a radius of 2 inches. Approximate, to the nearest degree, the angle β (see the figure) so that the cone
Aneli [31]
I don't know where the angle β is, so I will make the assumption that tanβ = h/r
V = \frac{1}{3} \pi r^{2} h

V volume = 60
r radius = 2
h = r tanβ

tan \beta = \frac{3V }{ \pi  r^{3} } = \frac{ 180}{25,1} = 7,17 \\  \\  \beta = 82
