Answer:
Use law of Cosines or Tangent
Step-by-step explanation:
This is a SAS triangle, where you have have an angle adjacent to two side lengths. But given that it is a right triangle, you can find the hypotenuse by just using the tangent formula. You can find the quantity of any angle by applying tan= opposite side/adjacent side length.
However, lets say you want to find the opposite side, side XZ, you can use the law of cosine which basically states:
c=a^2+b^2﹣2abcos(angle number). But since it is a right triangle, just use the hypotenuse theorem which states: C^2 = A^2 + B^2
The answer for XZ would thus be: squareroot of 136 or 2(34)^1/2.
Hope this helps :)
Answer:
x=30º
∠CAB=60°
∠ACB=80°
Step-by-step explanation:
Because the angles of every triangle add up to 180º, we know that:
x=30º
Plug that in for x on both angles, and you will get
∠CAB=60°
∠ACB=80°
Answer: The highlighted digit 8 is in the tens place. The value of the 8 is 80
Step-by-step explanation:
The value of the 8 is 80 becuse it is in the tens place.
4(y-3)=3(y+6)
1) Distribute
4y-12=3y+18
2) Addition property of equality
4y=3y+30
3)Subtraction property of equality
y=30
Thats your answer!
Enjoy middle school while you still can!
