Answer:
∠GDH = ∠GHD = 50°
Step-by-step explanation:
Angles FGD and EDG are alternate interior angles, so are congruent. That means angle EDG is 100°. The angle sum theorem tells us ...
∠EDG = ∠EDH +∠HDG
100° = 50° +∠HDG
50° = ∠HDG
You can find the measure of ∠DHG a couple of different ways. It is an alternate interior angle congruent to ∠EDH, so is 50°. It is one of two remote interior angles that have a sum equal to the exterior angle FGD, so is ...
∠DHG = ∠FGD -∠HDG = 100° -50° = 50°
So, angles DHG and HGD both have measures of 50°. When a triangle has two angles with the same measure, it is an isosceles triangle.
Answer:
Is there an error in the question? it has BC = 27 twice and we don't know much about the other sides. Anyway let's try
Step-by-step explanation:
You are told that to go from WXYZ to ABCD the scale factor is 2/3, which means that you multiply by 2/3. So to go the other way round, from ABCD to WXYZ which is what you want, you divide by 2/3, or multiply by 3/2.
So, to find XY you multiply the right side from ABCD by 3/2. I think BC is the right side?
So XY = 27 × 3/2
XY = 81 / 2 or 40.5 or 40 1/2
Answer:
x = 2
Step-by-step explanation:
6x - 5 = 13 – 3x
Add 3x to both sides
6x + 3x - 5 = 13 - 3x + 3x
9x - 5 = 13
Add 5 to both sides
9x - 5 + 5 = 13 + 5
9x = 13+5
9x = 18
Divide both sides by 9
9x/9 = 18/9
x = 2

Answer:
X^2-2X+1=0
Step-by-step explanation:
given,2X-X^2=1
or,-(X^2-2X)=1
or,X^2-2X=-1
or,X^2-2X+1=0 ,which is the req.equation in standard form.
Answer:
D) X = 11
Step-by-step explanation:
Solve for x
5x + 2 = 59
subtract 2 from both sides
5x = 57
divide both sides by 5
x = 57/5
this answer would be closest to x = 11 (11* 5 = 55)
