Answer:

$m\angle B=65\°$

$m\angle C=140\°$

Step-by-step explanation:

From the figure ABCD given:

$BC=CD$

$AB=AD$

$m\angle A=90\°$

$m\angle D=65\°$

The given figure ABCD is a kite as it fulfills the properties of a kite.

The properties of kite are:

1) It is 4 sided

2) It has 2 pairs of equal sides adjacent to each other.

3) The angles formed between the 2 pairs of sides is equal.

By the 3rd property of kite stated above:

$m\angle B=m\angle D$

Given $m\angle D=65\°$

∴ $m\angle B=65\°$

Sum of interior angle of a quadrilateral = 360°

So, we have $m\angle A+m\angle B+m\angle C+m\angle D=360\°$

Plugging in values of the angles known.

$90\°+65\°+m\angle C+65\°=360\°$

$m\angle C+220\°=360\°$

Using subtraction property of equality, we have

$m\angle C=360\°-220\°$

∴ $m\angle C=140\°$

A model ship has a mast that is 7 inches tall. A right triangular sail goes from the top of the mast to 1 inch from the bottom o

dezoksy [38]

Answer:

12 square inches.

Step-by-step explanation:

Please consider the complete question.

A model ship has a mast that is 7 inches tall. A right triangular sail goes from the top of the mast to 1 inch from the bottom of the mast. The length of the base of the sail is 4 inches. The height of the sail is along the mast. Find the area of the sail.

The sail will form a right triangle with respect to mast, whose height is 6 inches and base is 4 inches as shown in the diagram.

The area of the sail will be equal to area of triangle.

$\text{Area of triangle}=\frac{1}{2}(\text{Base}\times\text{Height})$

$\text{Area of triangle}=\frac{1}{2}(4\text{ in}\times6 \text{in})$

$\text{Area of triangle}=2\text{ in}\times 6 \text{in})$

$\text{Area of triangle}=12 \text{ in}^2$

Therefore, the area of the sail is 12 square inches.

When a number is decreased by 10 % of itself, the result is 126. What is the number?

iris [78.8K]

126 = (x)(.10)
126 = x0.10
126/0.10 = x
1260 = x

to check this answer:

(1260)(0.10) = 126

The number is: 1260

Solve the proportion<br><br>2x + 1/x + 1 = 14/3x-1

monitta

$\frac{2x+1}{x+1} = \frac{14}{3x-1} \ \ \Leftrightarrow\ \ (2x+1)(3x-1)=14(x+1)\ \ and\ \ x\in R-\{-1; \frac{1}{3}\}\\ \\6x^2-2x+3x-1=14x+14\\6x^2-13x-15=0\ \ \Rightarrow\ \ \Delta=(-13)^2-4\cdot6\cdot(-15)=169+360=529\\ \\ \sqrt{\Delta} =2\\ \\x_1= \frac{13-23}{2\cdot6} = \frac{-10}{12}=- \frac{5}{6}\ \in D\ \ \ and\ \ \ x_2= \frac{13+23}{2\cdot6} = \frac{36}{12}=3\ \in D$
