Answer:
<u>The correct answer is A. 10 - 2</u>
Step-by-step explanation:
1. Let's make all the comparisons for the four alternatives:
A. 3 + 7 > 10 - 2 ⇒ 10 > 8, the comparison is correct because 10 is bigger than 8.
B. 3 + 7 > 9 + 4 ⇒ 10 > 13, the comparison is not correct because 10 is less than 13.
C. 3 + 7 > 7 + 3 ⇒ 10 > 10, the comparison is not correct because 10 is equal to 10.
D. 3 + 7 > 8 + 2 ⇒ 10 > 10, the comparison is not correct because 10 is equal to 10.
<u>The only correct comparison is A. 10 - 2.</u>
Answer:
14 cm²
Step-by-step explanation:
Obtuse angle: more than 90° and less than 180°
The formula for the area of an obtuse triangle is the same as that for any triangle:
- area of a triangle = 1/2 x base x height
Therefore, given:
⇒ area = 1/2 x 4 x 7 = 14 cm²
