Mathematics
1 answer:
r-ruslan [8.4K]3 years ago
7 0

Answer:

x=4.5

Step-by-step explanation:

Using sohcahtoa we know tangent is equal to (length of side opposite to the angle ) / (lenth of side adjacent to the angle)

therefore: tan (theta) = (x-3) / (x) = 1 / 3

now cross multiply

3(x-3) = x

now solve for x

3x - 9 = x

-9= -2x

x= 4.5

Is anyone here in connections academy geometry. even if your not can someone help me with the question in the images. If correct
Inessa [10]

Answer:

13.05cm^2

Step-by-step explanation:

Area of a triangle is given a half the product of base by the perpendicular height:

A=0.5bh

Given h=9cm, and b=2.9cm, the area is calculated as:

A=0.5bh\\\\A=0.5\times 2.9cm \times 9cm\\\\A=13.05cm^2\\

Hence, area of the triangle is 13.05 sq cm

The linear equation y=3x−5y=3x−5 y equals 3 x , minus 5 is in what form.
Roman55 [17]
I must make some assumptions here about what you may have meant by your "<span>linear equation y=3x−5y=3x−5 y equals 3 x , minus 5."

You've written "y=3x-5" three times on the same line of type.  Why is that?  

Let's change what you've typed to the following:

</span><span>linear equation y=3x−5

separate linear equation y     equals 3x  minus 5, or y=3x-5 

Please go back and ensure that you have copied down this problem precisely as it was originally presented.  Be careful not to duplicate info (as you did in typing "y=3x-5," followed by  "</span><span>y equals 3 x , minus 5."
</span><span>
y = 3x - 5 is, as you say, "a linear equation."  The slope of this line is 3 and the y-intercept is (0, -5).

As to form:  This is a "slope-intercept equation of a straight line."

Other forms include "General form of the equation of a straight line," "Point-slope form."</span>

Answer:

15

Step-by-step explanation:

Let the smallest integer be x. The integers will be x, x+1, x+2, all the way up to x+6.

119 = 7x + (1+2+3+4+5+6)

119 = 7x + 21

7x = 98

x = 14

The second smallest integer will be x+1, so x+1 = 15.
