HALP ILL GIVE BRAINLIEST AND POINTS 1. A tree casts a shadow 8ft long. A 6ft man casts a shadow 4ft long. The triangle formed by the tree and its shadow is similar to the triangle formed by the man and his shadow. How tall is the tree?

2. An image on a slide is similar to its projected image. A slide is 35mm wide and 21mm high. Its projected image is 85cm wide. To the nearest centimeter, how high is the image?

Number one:

12 feet

Step-by-step explanation:

Draw a diagram (see picture below). The tree and its shadow is one triangle, the man and its shadow is another triangle. We assume both are right triangles because people and trees stand vertical.

Create a proportion to solve. Put the missing value in a numerator.

Tree height / Tree shadow = Man height / Man shadow

Solve using cross multiplication. Multiply x by 4. Multiply 6 by 8.

4x = 48 Divide both sides by 4 to isolate x.

x = 12 Height of tree

The tree is 12 feet tall.

Second one is the picture is put.

answer: the answer is 127 degrees

the answer is: the length is 5/6 yards.
