Use the relationships between angles to find the value of x
Answer:
x = 87
Step-by-step explanation:
The angles you see have a Corresponding Relationship so they are equal
x+15=102
x+15-15=102-15 (subtract 15 from both sides)
x=102-15
x = 87

3x - 31 = x + 59
Answer:
Let's solve your equation step-by-step.
3x−31=x+59
Step 1: Subtract x from both sides.
3x−31−x=x+59−x
2x−31=59
Step 2: Add 31 to both sides.
2x−31+31=59+31
2x=90
Step 3: Divide both sides by 2.

Find the missing length.
a
2.1 cm
2.9 cm
I NEED HELPPPP PLSSSS ITS FOR A MASTERY TEST PLSSSS HELPPPP
Answer:
a = 2
Step-by-step explanation:
To find the missing length we can use the Pythagorean theorem. Also, because it's a right triangle it makes it the perfect candidate!
The Pythagorean Theorem states:
a^2 + b^2 = c^2
Next, we substitute the letters with our given numbers (keep in mind that c is the hypotenuse which is the side facing the right angle)
a^2 + 2.1^2 = 2.9^2
Finally, we solve our equation (hint: use the calculator if needed)
a^2 = 4 (your answer is not final yet. You have to take the square root of both numbers)
a = 2 (Now that's the final answer!)

how does the Torah affect Jewish life today !!!!!!!
i will give brainlisttttt
Answer:
the Torah plays a big part in the lives of Jews today as it is believed to be the word of God. All Jews use the Torah to help guide them in their lives, but some Jews use the Torah more strictly than others. For example, some Orthodox Jews believe that it is important to follow every single rule in the Torah. However, Reform Jews tend to follow the rules they feel are most important and disregard some rules they see as outdated.
The significance of the Torah is seen in many ways:
It is read aloud weekly at the synagogue. It takes a year to recite the whole Torah.
The festival of Shavout celebrates God’s revelation of the Torah to Moses.
The commandments in the Torah shape the way that Jews live their lives today.
