To get the Greates Common Factor (GCF) of 84 and 210 we need to factor each value first and then we choose all the copies of factors and multiply them:
<span><span>84: 223 7</span><span>210: 2 357</span><span>GCF: 2 3 7</span></span>
<span>The Greates Common Factor (GCF) is: 2 x 3 x 7 = 42</span>
From 2 to 101 , the perfect square numbers are ,
- 4 , 9 , 16 , 25 , 36 , 49 , 64 , 81 , 100 .
Total number of possible outcomes = 100.
Total number of favourable outcomes = 9 .
Hence ,
→ <u>P ( of getting perfect square ) = 9/10</u><u>0</u>
Answer:
Step-by-step explanation:
We are given a ΔKLM, in which KL=LM=13 in and KM=10 in which means two sides of the given triangle are same and thus is an isosceles triangle.
Its median drawn from L to the KM will be altitude. Therefore, ΔKLN and ΔLMN are right triangles.
In ΔKLN, using the pythagoras property, we have
Now, Area of triangle= 1/2×base×height
=1/2×10×12
=60 squared inches.
Imagine there is a right angle triangle formed with the 30 degree angle and the 10 cm side forming the hypotenuse. Now, you can use trigonometry to calculate the height of this triangle, which is the same as the height of this shape.
So sin(30) = height/10
So, height = 5 cm<span />
