Work out the size of AED. Work out x
Answers
Answer:
a). m∠AED = 70°
b). x = 10°
Step-by-step explanation:
a). Quadrilateral ABDE is a cyclic quadrilateral.
Therefore, by the theorem of cyclic quadrilateral,
Sum of either pair of opposite angle is 180°
m(∠AED) + m(∠ABD) = 180°
m(∠AED) = 180° - 110°
m(∠AED) = 70°
Since, ∠AED ≅ ∠EAD
Therefore, m∠AED = m∠EAD = 70°
b). By triangle sum theorem in ΔABD,
m∠ABD + m∠BDA + m∠DAB = 180°
110° + 40° + m∠DAB = 180°
m∠DAB = 180° - 150°
m∠DAB = 30°
m∠BAE = m∠EAD + m∠BAD
= 70° + 30° = 100°
By angle sum theorem in ΔACE,
m∠EAC + m∠AEC + m∠ACE = 180°
100° + 70° + x° = 180°
x = 180° - 170°
x = 10°

write a linear equation that has a slope of 1/2 and a y-intercept at the origin. (y=1/2x) (y=0x+1/2) (y=1/2x+1/2) (y=-1/2x)
Answers
Answer:
The linear equation with given slope and y-intercept is:
Option 1: [tex]y = \frac{1}{2}x[/tex]
Step-by-step explanation:
The slope-intercept form of equation is given by:
[tex]y = mx+b[/tex]
Here
m is the slope of the line and b is the y-intercept.
Given that
Slope of line is 1/2 so m = 1/2
And y-intercept is on origin so b = 0
Putting the values we get
[tex]y = \frac{1}{2}x+0\\y = \frac{1}{2}x[/tex]
Hence,
The linear equation with given slope and y-intercept is:
Option 1: [tex]y = \frac{1}{2}x[/tex]

In one house , there are 5 hens, 10 goats and 8 cows. there are some man to look after them. If the number of heads is less than 65, then the number of man will be
Answers
Answer:
Pretty sure is 42
Step-by-step explanation:
5+10+8=23
65-23=42
The number of men will be 42 if there are 5 hens, 10 goats, and 8 cows.
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
We have:
In one house, there are 5 hens, 10 goats, and 8 cows.
Let H be man's head
H < 65
Total heads = 5 + 10 + 8 =23
Man's heds = 65 - 23 = 42
Thus, the number of men will be 42 if there are 5 hens, 10 goats, and 8 cows.
