Answer:
a. x = 24
b. x = 40
Step-by-step explanation:
a.
You are given a right triangle, so use the Pythagorean theorem
a^2 + b^2 = c^2
x^2 + 18^2 = 30^2
x^2 + 324 = 900
x^2 = 576
x = 24
b.
The sum of the measures of all angles is 360 degrees.
x + 2x + 2x + 20 + 3x + 20 = 360
8x + 40 = 360
8x = 320
x = 40
<h3>
You have the correct answer. It is choice B. Nice work.</h3>
K is the midpoint, so and , and along with the congruent vertical angles ( and ), you would use the SAS (side angle side) congruence theorem to prove the inner pairs of triangles to be congruent.
So, (top and bottom triangles) and (left and right triangles).
Then through CPCTC, we can show the corresponding pieces are congruent leading to and showing the opposite sides of the quadrilateral are congruent. Therefore we do have a parallelogram and enough information to prove it as such.
Side note: CPCTC stands for "corresponding parts of congruent triangles are congruent".
Answer:
Option A.
Step-by-step explanation:
The given expression is
We need to find the difference round to the less precise measurement.
Taking out the common factor.
Precise measurement of given expression is 81.2g.
A measurement with more decimal places is more precise and vice versa.
Now, approx the answer to the the nearest whole measure.
The less precise measurement of given expression is 81g.
Therefore, the correct option is A.
