Trees take in carbon dioxide and other gases that we cannot breathe in and gives us oxygen. It also helps other plants and animals nourish themselves. To some animals, trees are their habitat so by planting more trees, we are technically building a habitat for plants and animals to live in. It's also good shade on a sunny day.
Answer:
B =48
Explanation:
To solve this problem we need to know that ALWAYS the sum of complementary angles are equeal to 90.
If A is complementary to angle B, we can affirm that:
A+B=90.
Given that A=42, solving for B:
B = 90 - A = 90 - 42 = 48
Then, the measure of angle B is 48.
