Answer:
x = 27976.22021
Step-by-step explanation:
10x + .0085x = 280000
Combine like terms
10.0085x = 280000
Divide by 10.0085 on each side
10.0085x /10.0085= 280000/10.0085
x = 27976.22021
Answer:
43.234%
Step-by-step explanation:
40 Percent of 285= 14.035%
60 percent of 980 = 6.122%
75 percent of 325 = 23.077%
Sum is 43.234%
Answer:
180°
Step-by-step explanation:
The diagram for this question has been attached to this response.
From the diagram;
(i) ∠2 and ∠6 are equal since they are corresponding angles. This implies that the measure of angle 2 (m∠2) is equal to the measure of angle 6 (m∠6). i.e
m∠2 = m∠6 ---------(a)
But m∠2 = 40°
<em>Substitute this into equation (a) as follows;</em>
40° = m∠6
∴ m∠6 = 40°
(ii) ∠1 and ∠2 are supplementary. This implies that the sum of the measures of angle 1 (m∠1) and angle 2(m∠2) is equal to 180°. i.e
m∠1 + m∠2 = 180° ------------------(b)
But m∠2 = 40°
<em>Substitute this into equation (b) as follows;</em>
m∠1 + 40° = 180°
m∠1 = 180° - 40°
m∠1 = 140°
(iii) The measure of ∠1 + ∠6 is given by;
m∠1 + m∠6
<em>Substitute the values of m∠1 = 140° and m∠6 = 40° into the expression to get</em>
m∠1 + m∠6 = 140° + 40°
m∠1 + m∠6 = 180<em>°</em>
<em />
Therefore the measure of ∠1 + ∠6 is 180°
