Use the Pythagorean theorem to find z:
z = √(6^2 + 9^2)
z= √(36 + 81)
z = √117
z = 3√13 = 10.8
Use leg rule to find x:
x/6 = 6/9
Cross multiply:
9x = 36
Divide both sides by 9:
x = 36/9
x = 4
Use Pythagorean theorem to find y:
y = √(6^2 + 4^2)
y= √(36 + 16)
y = √52
y = 2√13 = 7.2
Answer:x=−24/11
Step-by-step explanation:
Simplifies to:
x−86x=79
Let's solve your equation step-by-step.
x−86x=79
Step 1: Cross-multiply.
x−86x=79
(x−8)*(9)=7*6x
9x−72=42x
Step 2: Subtract 42x from both sides.
9x−72−42x=42x−42x
−33x−72=0
Step 3: Add 72 to both sides.
−33x−72+72=0+72
−33x=72
Step 4: Divide both sides by -33.
−33x−33=72−33
x=−2411

The first term and common ratio for the geometric sequence are -3 and 5 respectively
<h3>Geometric sequence</h3>
This are sequence that increases exponentially. The nth term of the sequence is given as:
Tn = ar^n-1
where;
a is the first term
r is the common ratio
n is the number of terms
ar = -15
ar^3 = -375
Divide
r^2 = 375/15
r^2 = 25
r = 5
Determine the first term
a= -15/r
a = -15/5
a = -3
Hence the first term and common ratio for the geometric sequence are -3 and 5 respectively
