Answer:
the third choice
Step-by-step explanation:
L+10+2L-3+L=503
I used the variable "L" instead of z
Answer:
m = -2.5
b = 5
Step-by-step explanation:
y = mx + b
Answer:
<h3>1863 m squared</h3>
Step-by-step explanation:
So, the goal here is to find the area of each block individually then add it all together. In other words, you're gonna look for a way to solve for the missing square in the total large rectangle. Keep in mind 23 + 23 + 23 = 69 (aka the length of the whole rectangle)
So:
12 x 23 = the missing square = 276
31 x 69 = rectangle with the square = 2139
Total area = 2139 - 276 = 1863
Answer:
see explanation
Step-by-step explanation:
Using the Sine rule in all 3 questions
(1)
= 
, substitute values , firstly calculating ∠ B
[ ∠ B = 180° - (78 + 49)° = 180° - 127° = 53° ]
= 
( cross- multiply )
a sin53° = 18 sin78° ( divide both sides by sin53° )
a = 
≈ 22.0 ( to the nearest tenth )
(3)
= , substitute values
= 
( cross- multiply )
45 sinC = 35 sin134° ( divide both sides by 35 )
sinC = 
, then
∠ C = 
( ) ≈ 34.0° ( to the nearest tenth )
(5)
Calculate the measure of ∠ B
∠ B = 180° - (38 + 92)° = 180° - 130° = 50°
= , substitute values
= 
( cross- multiply )
BC sin50° = 10 sin38° ( divide both sides by sin50° )
BC = 
≈ 8.0 ( to the nearest tenth )
The right answer for the question that is being asked and shown above is that: "A. quadrilateral with one side longer than the other." This is the best statement that describes the figure with precise language: <span>quadrilateral with one side longer than the other</span>
