Triangle ABC is a right triangle and cos(22.6)=b/13. Slobs for b and round to the nearest whole number
aliina [53]
<u>Answer</u>
12


<u>Explanation</u>
Cosine is the ratio of adjacent to hypotenuse.

So, in this case b is the adjacent and 13 is the hypotenuse.

cos22.6 = b/13
b = 13×cos22.6
    = 13×0.923879532
    =12.010

To the nearest whole number the answer is 12.

(1+m)²= (1-m)²+ 4lm,​
ehidna [41]

The expression is simplified to give 2 ( m² + m + 2Im ) = 0

<h3>How to simplify the expression</h3>

Given the expression;

(1+m)²= (1-m)²+ 4lm,​

Expand the expression

( 1 +m) ( 1 + m) = ( 1 + m) ( 1 - m) + 4Im

1 + m + m + m² = 1 - m + m - m² + 4Im

collect like terms

1 + 2m + m² = 1 - m² + 4Im

1 - 1 + m² + m² + 2m + 4Im

2m² + 2m + 4lm = 0

simplify

2 ( m² + m + 2Im ) = 0

Thus, the expression is simplified to give 2 ( m² + m + 2Im ) = 0

The vertices of △ DEF are D (2, 5), E (6, 3), and F (4, 0). Translate △ DEF using the given vector. Graph △ DEF and its image. T
jeyben [28]

Answer:

The image coordinates are D'(8, 5), E'(12, 3) and F'(10,0)

Step-by-step explanation:

Given the vertices of △ DEF are D (2, 5), E (6, 3), and F (4, 0). We have to translate the triangle using the vector (6, 0)

Now, translation by vector (6, 0)

D (2, 5)=D'(2+6, 5+0)=D'(8, 5)

E (6, 3)=E'(6+6, 3+0)=E'(12, 3)

F (4, 0)=F'(4+6, 0+0)=F'(10,0)

Now, we have to label the coordinate of the triangle or to get image of triangle after translation.

Hence, The image coordinates are D'(8, 5), E'(12, 3) and F'(10,0)
