Answer: the numbers were negative so he needed to add the positive numbers to that equation (I think sorry if I’m wrong)
Step-by-step explanation:
Answer:
2) d. 60°
3) a. AB
Step-by-step explanation:
<u>Question 2</u>
ΔABC and ΔCDA are <u>congruent</u> because:
- they are both <u>right triangles</u>
- they <u>share one side</u> (AC)
- their hypotenuse are <u>parallel</u> (marked by the arrows)
This means the corresponding side lengths and angles are equal.
Therefore,
∠CDA = ∠ABC
⇒ x = 60°
<u>Question 3</u>
The <u>hypotenuse</u> is the <u>longest side</u> of a <u>right triangle</u> - the side opposite the right angle (the right angle is shown as a small square).
Therefore, the hypotenuse of ΔABC is the line AB.
Answer:
9.89949 or 9.9
Step-by-step explanation:
7^2 + 7^2 = c^2
49+49=98
square root of 98 = 9.89949
Answer:
9
Step-by-step explanation:
We know that a=1/5. Therefore, we can substitute 1/5 in for a into the expression.
10a + 7
10(1/5)+7 <em>Multiply 1/5 and 10</em>
2+7 <em>Add 2 and 7 </em>
9
