Answer:
Step-by-step explanation:
geometric progression formula:
given:
common ratio, r = 1/2
1) find the value of a
we're finding the 1st term, so substitute 1 into n:
first term is 5. so we substitute 5 into the equation:
2) find the 10th term
we're finding the 10th term, so substitute 10 into the equation and don't forget to substitute 5 into a:
Answer:
(25 * 5.5) + (x * 2.9) + [(25 - x) * 4.4] = 50 * 4.5
Step-by-step explanation:
0.5 * 50Lbs. = 25 Lbs.
12.5 Lbs
12.5 Lbs.
The measurement of fourth angle is: 130°
Further explanation:
Let A, B, C and D be the four angles.
m∠A=105°
m∠B=80°
m∠C=45°
We know that the sum of interior angles of a quadrilateral is 360°
So,
m∠A+m∠B+m∠C+m∠D=360°
105°+80°+45°+m∠D=360°
230°+m∠D=360°
m∠D=360°-230°
m∠D=130°
The measurement of fourth angle is: 130°
