Answer:

a=12

Step-by-step explanation:

Pythagorean Theorem: a^{2}+b^{2}=c^{2}

In this case, a = 9, b = a, and c = 15.

9^{2}+a^{2}=15^{2}

81+a^{2}=225

The, we subtract 81 from both sides getting:

a^{2}=144,

Then, a=12

5 x {3 x [9 - (4 + 1)]} + 20 ÷ 4 x 2 =
adell [148]
To solve a problem like this, we need to start with the innermost parenthesis. Doing that, we get to 4+1, evaluating it giving us 5. This turns our expression into 5 x {3 x [9 - 5]} + 20 ÷ 4 x 2.



Now, the innermost parenthesis is 9-5. Evaluating that gives us 4. Our expression is now 5 x {3 x 4} + 20 ÷ 4 x 2.



Once again, we go to the innermost parenthesis and evaluate whatever is there. This turns our expression into <span>5 x 12 + 20 ÷ 4 x 2.



Now, we can simply use order of operations to compute that the value of the expression is equal to 70. </span>
