I think the first photo, to find the answer, you have to add two sides together. If they are greater than the third, it’s a triangle. If not, then it’s not a triangle.

For A on the slide with 4 cards, the two angles labeled x are equal to each other. A triangle has 180 degrees. Subtract the given angle from 180 and divide by two.

I think those clues can Apple to most of the other pictures. That’s the most I can remember from my geometry class.

Elan Coil [88]

Answer:

34.72 feets

Step-by-step explanation:

Using the relation :

Length of tree / shadow of tree = height of melody / shadow of melody

From the details given in the question :

Let height of tree = h

h / 62 = 5.6 / 10

Cross multiply

h * 10 = 62 * 5.6

h = 347.2 / 10

h = 34.72 feets

Hence, the height of tree is 34.72 feets
