Answer:
Step-by-step explanation:
BC=AD
3x-1=x+5
3x-x=5+1
2x=6
x=3
BC=3×3-1=8
CD=2x=2×3=6
perimeter=2(8+6)=2(14)=28
Answer:
the inequality woulds be *less than
Step-by-step explanation:
Given:
In triangle KLM, KL = 123 cm and measure of angle K is 35 degrees.
To find:
The length of the side KM to the nearest tenth of a centimeter.
Solution:
In a right angle triangle,

In the given right triangle KLM,



Multiply both sides by 123.



The measure of side KM is 100.8 cm.
Therefore, the correct option is (2).
The answer is 0.027, you are correct. 0.3 to the third power means 0.3 x 0.3 x 0.3 and that equals 0.027
