Answer:

Step-by-step explanation:
First we solve for the biggest triangle: using the Pythagorean theorem, (a^2 + b^2 = c^2) we put in the sides,
9^2 + b^2 = 10^2.
solve, 81 + b^2 = 100
then we subtract 81 from both sides. b^2 = 19, and the answer is
.
Now we know what the third side is, which is the hypotenuse for the smaller triangle, so we use the Pythagorean theorem again.
4^2 + x^2 = 19.
Solve
16 + x^2 = 19
Subtract 16 from both sides
x^2 = 19
and finally, we take the square root of both sides
x = 
56 = 1 x 56, 2 x 28, 4 x 14, or 7 x 8.
Answer:
2650
Step-by-step explanation:
Given: 2648
Two significant figures means we need to round off to the nearest tens place.
In 2648, the tens place is 4
To round off the tens place, we need to look for the next digit that is right to tens place, which is 8
8 is greater than 5, so we need to add 1 with tens place (4 +1 = 5)
Therefore, it is 2650
Hope this will helpful.
Thank you.
Answer:
? = 68°
Step-by-step explanation:
The inscribed angle ? is half the measure its intercepted arc.
The sum of the 3 arcs = 360°, thus
intercepted arc = 360° - (134 + 90)° = 360° - 224° = 136°, so
? = 0.5 × 136° = 68°
