Answer:
Not a right triangle.
Step-by-step explanation:
We can tell if it's a right triangle or not by using the Pythagorean Theorem.
The largest value is always the hypotenuse (c).
a² + b² = c²
24² + 70² = 75²
576 + 4900 = 5625
5476 ≠ 5625
The values do not equal one another. Therefore, this triangle is NOT a right triangle.
Answer:
144 u²
Step-by-step explanation:
first we need to find lateral area
La=Ph
LA=(12)(11)
LA= 132 u²
SA= Ph + 2B
SA= 132 + 2(6)
SA= 144 u²
Answer:
-14√2
Step-by-step explanation:
Note that 18 = 2*9, and that 9 is a perfect square. Therefore,
2*√18 = 2*3*√2, or 6√2.
Next, note that 32 = 2*16, and that 16 is a perfect square. Therefore,
-5*√32 = -5*√2*√16, or -5*√2*4, or -20√2.
Combining these two results, we get:
6*√2 - 20√2, or -14√2
Answer:
<2=65 degrees
Step-by-step explanation:
Information provided:
Right angle=90
<25 degrees
Triangles add up to 180 degrees
90+25=115
180-115=65 degrees
Hope this helps! :)
