Answer:
About 30.904 cm.
Step-by-step explanation:
The equation is A=1/2(a+b)h
Where A=22.2
B=8.52
C= 9.86
X - the number
To decrease the number by 3% you subtract 3% of the number from the number.
![x-3\%x = 100\%x-3\%x=97\% x=0.97x](https://tex.z-dn.net/?f=x-3%5C%25x%20%3D%20100%5C%25x-3%5C%25x%3D97%5C%25%20x%3D0.97x)
The multiplier you would use is
0.97.
Answer:
x1.20
y0.75)
Step-by-step explanation:
you have to simplify
X=12. So this one says that it has 3 congruent sides so therefore it has to have 3 congruent angles. Here we have angle 2 and we have angle 60. Given the definition of triangle congruence, we can say that 60 is angle 2 and that the third angle is also 60 but it’s not relevant in this problem. So knowing that angle 2 is 4x+12 we solve for x by seeding that equal to 60 and then solving for x we get x=12. Hope this helps!!!!
<span>If triangle ABC is congruent to triangle XYZ
then
<A = <X
