Answer:

56°, 84°, 40°

Step-by-step explanation:

The three angles of triangles have measures of 56°, (2x + 4)º, and xº.

We need to find the measures of the three angles of the triangle.

We know that, the sum of angles of triangle is equal to 180º. Using this property we get :

56°+ (2x + 4)º + xº =180º

Solving for x.

60 + 3x = 180

3x = 120

x = 40º

Other angle, = 2x+4

= 2(40)+4

= 80+4

= 84º

So, the measures of the three angles of the triangle are 56°, 84°, 40°. Hence, the correct option is (c).

Triangle base is 2.4 what is the height

Fantom [35]

Answer:

Hello!

To answer your question, consider the Pythagorean Theorem- a²+b²=c²

In this case, a would be 2.4/2= 1.2

I cannot answer your question fully because at least two of the three letters should be known in order for the formula to work, as well as to find the height. Was the slant height given?

Twelve more than 3 times a number is more than the opposite of 11

aleksley [76]

Answer: n > $\frac{-23}{3}$

Step-by-step explanation:

1. So, to understand this you need to understand that the opposite of 11 is -11.

2. Use the formula 3n+12>-11.

3. Subtract 12 from both sides (3n>-23)

4. Divide by 3 on both sides. (n> $\frac{-23}{3}$ )

5. You can go a step further and simplify into -7 $\frac{2}{3}$ .

6. n > $\frac{-23}{3}$

Diano4ka-milaya [45]

Answer:

2.60

Step-by-step explanation:

Given that:

n = 1600

$\hat p = 0.34$

$P_o = 0.31$

The test statistics can be computed as:

$Z = \dfrac{\hat p - P_o}{\sqrt{ \dfrac{P_o\times (1-P_o) } {n} }}$

$Z = \dfrac{0.34-0.31}{\sqrt{ \dfrac{0.31 \times (1-0.31) } {1600} }}$

$Z = \dfrac{0.03}{\sqrt{ \dfrac{0.31 \times (0.69) } {1600} }}$

$Z = \dfrac{0.03}{\sqrt{ \dfrac{0.2139} {1600} }}$

$Z = 2.60$
