Can some find the area to this triangle I tried a bunch of things and i keep getting it wrong

Dafna1 [17]

Answer:

The answer to your question is 287.52 u²

Step-by-step explanation:

To calculate the area of a triangle it is necessary to have the base and the high of this figure.

Base = 35 km

height = ?

To calculate the height draw a right triangle and use the trigonometric function sin to find it.

sin Ф = $\frac{opposite side}{hypotenuse}$

Opposite side = hypotenuse x sinФ

Opposite side = height = 37 x sin28

= 16.43 km

Calculate the area

Area = (1/2)(35)(16.43)

Area = 287.52 u²

lapo4ka [179]

The pints of vegetable stock the chef needs is $3\frac{1}{2}$ .

<h3>How many pints does he need?</h3>

The first step is to determine the unit of conversion of cups to pints.

1 cup = 0.5 pints

To convert cup to pints, multiply 7 by 0.7

7 x 0.5 = 7/2 = $3\frac{1}{2}$

Help me please with this

Paha777 [63]

11) 2x+6y-3; x=5,y=4
the question is asking to evaluate for y when x=5 and evaluate for x when y=4,

2x+6y-3
2x+6y=3

2(5)+6y=3
10+6y=3
6y=3-10
y=-7/6 when x=5

2x+6(4)=3
2x+24=3
2x=3-24
x=-21/2 when y=4

12)
Input Output
N 4(n+3)
12 4(12+3) = 4(15)=60
14 4(14+3)=4(17)=68
18 4(18+3)=4(21)=84
25 4(25+3)=4(28)=112

13)8x+y-10; x=4, y=50
8x+y=10
8(4)+y=10
32+y=10
y=10-32
y=-22 when x=4

8x+50=10
8x=10-50
8x=-40
x=-40/8
×=-5/1=-5 when y=50

14) b is correct

15)c is correct

16) c is correct
