Answer:
z = 69°
Step-by-step explanation:
The sum of all interior angles in a quadrilateral is 360°, and a right angle is worth 90°. We're given the values of the interior angles as 90, 122, 79, and z degrees.
- We can solve this question algebraically with the equation
Step 1: Combine like terms.
Step 2: Subtract 291 from both sides.
Step 3: Check if solution is correct.
Therefore, z = 69°.

Answer:
Step-by-step explanation:
using pythagoras theorem
a^2 + b^2 = c^2
B^2 + 8^2 = 15^2
B^2 + 64 + 225
B^2 = 225 - 64
B^2 = 161
B =
OR 12.7
20%=20÷100=0.2 then add 2000+0.2 the answer would be 2200 for 30 days

Answer:
The Time in which sum of money double itself is 14 years .
Step-by-step explanation:
Given as :
The principal money = P
The rate of interest = R = 5 % payable half yearly
The Amount = Double of principal
Let The time in which sum become double = t years
I.e A = 2 P
<u>From Compounded method</u>
Amount = principal × 
or, 2 P = P × 
Or, 2 = 
Or, Taking log with base 10 both side
So,
2 =

or, 0.3010 = 2 t ×
1.025
Or, 0.3010 = 2 t × 0.010723
Or, 0.3010 = 0.021446 t
∴ t = 
I.e t = 14.03 years ≈ 14 years
So, The time period = T = 14 years
Hence The Time in which sum of money double itself is 14 years . Answer
