Answer:
27
Step-by-step explanation:
The triangle shown is an isoceles triangle. This means that there are two congruent base angles and a vertex angle. In this case, angle X and angle Y are the base angles, so we can set up an equation to first find the value of t.
5t - 13 = 3t + 3
2t - 13 = 3 (Subtract 3t from both sides)
2t = 16 (Add 13 to both sides)
t = 8 (Divide both sides by 2)
Now that we have the value of t, we can plug it back in to the expression for angle X to find its measure.
5(8) - 13
40 - 13
27
So, the measure of angle X is 27
Answer:
$57
Step-by-step explanation:
$380x0.85=$323
$380-$323=$57
Answer:
I won't write it in paragraph but use this:
- angle A + angle B + angle C = 180 so when one angle is missing add the other 2 and subtract it to 180, that would be the answer for the missing angle; applies only to triangle (all kinds)
- if its the exterior angle, add them all like the one above but subtract it instead to any shapes or if it is adjacent to a given degree, you can always subtract it to 180 to get the exterior
- if its a different shape, count the sides and subtract it by two then multiply by 180; thats the degree for the total angles of the shape
- if its variable, do the third one (unless you know what it is) add them all like the first one and subtract to the answer in the #3
Total amount = $80
Amount left= $54.74
So amount spent = 80 - 54.74 = $25.26
Let the number of pounds be ‘x’
8.42 x = 25.26
x = 3
Ans: She bought 3 pounds of coffee
The answer is (base×height)÷2
