Sides in ascending order:
AB = 17, AC = 18, BC = 21Angles in same order
∠C, ∠B, ∠AQ14As above, sides in ascending order:
AB = 15, AC = 16, BC = 17Angles in same order
∠C, ∠B, ∠AQ15Exterior angle equals to sum of non-adjacent interior angles
142° = x + 66°x = 142° - 66°x = 76°Q16Same subject and isosceles triangle:
x + x = 158°2x = 158°x = 79°Q17Same subject
m∠QSR = m∠QPS + m∠PQS2x = x + m∠PQSm∠PQS = 2x - xm∠PQS = xΔPQS has two angles with the measure of x, hence their opposite sides are congruent and the triangle is isosceles

What is the measure of ∠BCE, in degrees, in the figure shown?
Answers
Answer:
25 degrees
Step-by-step explanation:
So a triangles angels equal 180 degrees
So for angel ECD 180 - (15+90) = 75
Straight lines also always equal to 180 degrees so
180 - (80+75) = 25
Measure of ∠BCE = 25° .
What is angle?A figure which is formed by two rays or lines that shares a common endpoint is called an angle. The word “angle” is derived from the Latin word “angulus”, which means “corner”.
Given, In figure,
∠CED = 15°
∠EDC = 90°
∠BCA = 80°.
In triangle ECD
Sum of all interior angles of a triangle is 180°
∠ECD +∠CED +∠EDC = 180°
∠ECD + 15° + 90° = 180°
∠ECD = 180° - 105°
∠ECD = 75°
Now,
∠BCA,∠BCE and∠ECD are at point C on line AD.
Sum of all angles made at one point of line is 180°.
∠BCA +∠BCE +∠ECD = 180°
80° + ∠BCE + 75° = 180°
∠BCE = 180° - 155°
∠BCE = 25°
Hence, 25° is measure of ∠BCE.

Explanation:
5x-15=10
Answer:
x = 7
Step-by-step explanation:
You need to figure which sides correspond and set up the proportions
Labeling the vertices of the triangles would help you.
I did that and found that 5x - 15 ↔ 10 since both of those sides are opposite the 42° angles and 36 ↔ 18
So [tex]\frac{5x - 15}{10} = \frac{36}{18\\}[/tex]
18(5x - 15) = 10(36)
90x - 270 = 360
90x = 630

Oliver expects that the number of visitors to a museum(y) is related to the daily rainfall in mm(x). He plots a scatter plot and determines the equation for the line of best fit: y=14.1x+62.0 What is the expected number of visitors when the daily rainfall is 20 mm? Give your answer to the nearest integer.
Answers
Answer:
344 visitors
Step-by-step explanation:
Given that the relationship between the number of visitors to a museum(y) and the daily rainfall in mm(x) is defined as
y=14.1x+62.0
when the daily rainfall is 20 mm, the number of visitors
y = 14.1(20) + 62
= 282 + 62
= 344
It means that the expected number of visitors is 344 persons (to the nearest integer).

Please help!!!!!!!! With explanation!!!!!
Answers
Answer:
a = 72° b = 88°
Step-by-step explanation:
We know in the cyclic quadrilateral opposite angles are supplementary so
a + 108° = 180° { being opposite angles of cyclic quadrilateral }
a = 180° - 108°
a = 72°
b + 92° = 180° { being opposite angles of cyclic quadrilateral }
b = 180° - 92°
b = 88°
