Answer:
ASA
Step-by-step explanation: I'm not sure I had just found a key.
There is only 1 remaining side
We have 2 sides and an included angle, we use the Law of Cosines to solve the third side:
c^2 = a^2 + b^2 -2ab *cos(C)
c^2 = .5^2 + .333333333...^2 - 2 * .5 * .3333333... * cos (95)
c^2 = .25 + .1111111111111111... -2*.5*.3333333333...* -0.087156
c^2 = 0.3611111111 + 0.029052
c^2 = 0.3901631111
c = 0.6246303796
Answer:
36 units.
Step-by-step explanation:
we will use concept of basic proportionality theorem,
it states that , when a line is drawn parallel to one side of the triangle and intersect the other two sides then the two sides are divided in the same ratio.
Example:
In a triangle ABC
If DE is parallel to BC
D is a point on line AB and E is point on AC, then
by basic proportionality theorem)
AD/DB = AE/EC
_____________________________________
in the problem given one side has a parallel line drawn to it
Hence we can use basic proportionality theorem in it
20/30 = 24/?
2/3 = 24/?
=> ? = 24*3/2 = 36
Hence, missing segment value is 36 units.
This is markdown, thus once again, two equations.
Markdown=Original-New
and
Markdown%=Markdown Amount/Original*100
Markdown=10-3
Markdown=7
Markdown%= 7/10*100
=0.7*100
=70
Thus, the percent decrease/Markdown is 70%.
Answer:
272 yd²
Step-by-step explanation:
Surface area = base area + lateral area
= (10×10)+(8.6×10×2)
= 100+172
= 272 yd²
