Step-by-step explanation:
for triangle HLM
180-2x
180-(3x+6)
H
2x=3x-10
x=10°
180-36=144°
36-20=16°
H=2x
H= 180-144-16= 20°
F(1) is the first term of the arithmetic sequence, then f(1)=-9
Common difference: 7
-2-(-9)=-2+9=7
5-(-2)=5+2=7
12-5=7
Answer: Fourth option
f(1)=-9
Common difference: 7
Answer:
The answer is 540 mm^3
Step-by-step explanation:
using v= BH
v= 30×18
v= 540mm^3

Question 1:Use the Pythagorean theorem.
If

, then the angle is acute.
If

, then the angle is right.
If

, then the angle is obtuse.






Thus, the angle is acute.
Question 2:Take the square root of the area to get the side length.

That's the side length. Since we have a 45-45-90 right triangle if we divide the square across its diagonal, we just multiply the side length by the square root of 2 in order to get the diagonal length.


Your answer is 20 m. Hope this helps! :)
