U would simpiphy it to then get the awnser
Answer:
x is tangent of 39 = x/ 19, tangent of 39 is 3. 615...... then 19 multiply by 3.615....., x would get 68. 68
Step-by-step explanation:
tangent is opposite over adjacent then put all your numbers in to the formula.
Answer:
2
Step-by-step explanation:
Since there is nothing to solve in the absolute value, take them away and make -2x just 2x. To get x by itself, divide both sides by 2 to get x=2
Hello!
To find the surface area you can divide the prism into the 2D shapes it is made of
First list out all the shapes
2 triangles with bases of 18 and heights of 15.6
3 rectangles with side lengths of 20 and 18
First find the area of the triangles
The equation to find the area of a triangle is
A is area
h is height
b is base
Put in the values you know
Solve
A = 140.4
The triangles have an area of 140.4 units
Next we find the area of a the rectangles
To do this we multiply the sides
18 * 20 = 360
The rectangles have areas of 360 units
Now we add all the areas
There are 2 triangles and 3 rectangles
140.4 + 140.4 + 360 + 360 + 360 = 1360.8
The answer is B) 1360.8cm squared
Hope this helps!
Answer:
x = 8
Step-by-step explanation:
since it's a collinerar
or, AB+BC=AC
or, 3x+5x+10 = 74
or, 8x = 74-10
or, 8x = 64
or, x = 64/8
x = 8
