Answer:
The measure of angle x is 90°
Step-by-step explanation:
Given the figure in which
∠1=88°, ∠6=89°
we have to find the value of x.
∠5=∠6=89° (∵ Vertically opposite angles)
∠1+∠4=∠6 ( ∵ By exterior angle property)
88°+∠4=89°
∠4=89°-88°=1°
As AC=CB (both are radii of same circle)
∴ ∠4=∠3=1°
Now, by exterior angle property
x=∠5+∠3=89°+1°=90°
Hence, the measure of angle x is 90°

Answer:
Area = 492.4 m²
Explanation:
The area of the triangle can be calculated using the side-angle-side method as follows:
Area = 0.5 * first side * second side * sin(angle included between these two sides)
This rule is illustrated in the attached image.
Now, we have:
AB = 40 m
BC = 25 m
angle B which is the angle included between AB and BC = 80 degrees
The given angle is included between the two given sides, therefore, we can apply the above rule to get the area.
Area of triangle = 0.5*40*25*sin(80)
Area of triangle = 492.4 m²
Hope this helps :)
