Answer:
JML=126 (x=42)
Step-by-step explanation:
Since the whole angle is equal to 180, you take that and subtract it by the part of that angle you know. The remainder is JML. If you want to find x, you set 3x equal to 126.

Answer:
firstly the angle a is 42
so x will be 180-42=138
Answer:
26.8
Step-by-step explanation:
x/145 = 18.5/100
cross-multiply:
100x = 2682.5
x = 26.8
If the rate is at Rs7 per meter square, the cost of laying grass in a triangular field will be Rs150150
<h3>Surface area of triangular field</h3>
The formula for calculating the surface area of a triangular field is expressed as;
Surface area = 2(lw+lh+wh)
Substitute the given dimension
Surface area = 2(50(65)+50(65) + 65(65))
Surface area = 2(3250+3250+4225)
Surface area = 2(10725)
Surface area = 21450 square meters
If the rate is at Rs7 per meter square, the cost of laying grass in a triangular field will be Rs150150
