Answer:
90.5 degrees
Step-by-step explanation:
The sum of the angle in triangle XYZ is 180 degrees, hence;
m<XYZ + m<YXZ + <XZY = 180
Substitute the given angles
75 + 14.5 + <XZY = 180
89.5+m<XZY = 180
m<XZY = 180 - 89.5
m<XZY = 90.5 degrees
Hence the measure of angle XZY in degrees is 90.5 degrees
<h3>
Answer: 1.8x - 4</h3>
==========================================================
Explanation:
Subtract the two expressions
Tomas - Angie = (3x) - (1.2x+4) = 3x - 1.2x-4 = 1.8x-4
This represents how many more miles Tomas jogged compared to Angie.
-------------
A more concrete example would be to say hypothetically
Tomas = 10 miles
Angie = 4 miles
So Tomas - Angie = 10-4 = 6 means he jogged 6 more miles than Angie.
That's why we subtracted. The order of subtraction matters. Saying 10-4 is different from 4-10.
Answer:

Step-by-step explanation:
So we have the equation:

And we want to write it in terms of m.
So, let's subtract b from both sides:

Now, let's divide both sides by x:

And we're done!
The correct answer is option B that is Each white blood cell contains millions of haemoglobin molecules. All blood cells come from one pool of stem cells.
The complete question is given below:-
Which of the following statements are true?
I. Each white blood cell contains millions of haemoglobin molecules.
II. In a sample of blood, there are more red blood cells than white blood cells.
III. HIV destroys red blood cells.
IV. All blood cells come from one pool of stem cells.
A. II and IV only
B. I and IV only
C. II and III only
D. I, III, and IV only
E. I, II, and IV only
<h3>What are blood cells?</h3>
The most prevalent form of blood cell and the main source of oxygen for the bodily tissues of vertebrates, red blood cells are also known as red cells, red blood corpuscles, haematids, erythroid cells, or erythrocytes. They circulate through the blood through the circulatory system.
Therefore the correct answer is option B that is Each white blood cell contains millions of haemoglobin molecules. All blood cells come from one pool of stem cells.

I'd go with your third option, 6.
Half the diameter (the radius, also the hypotenuse for the right triangle) is 10 units.
Half of the chord given by that blue line segment is 8 units. Now we do the Pythagorean Theorem (a² + b² = c²) to find the length of x.
x² + 8² = 10²
x² + 64 = 100
x² = 36
√x² = √36
x = 6
