Answer:
x = 71°
Step-by-step explanation:
because the triangle shown in the image is an isosceles if the top angle is 38 the sum of other two angles must be 142 which is ,if divided by 2, makes 71
X = 71°
Fierst of all that's an isosceles Triangle.
Isosceles triangle are triangles that have two sides and two angles equal .
To determine mine x, we are given one angle to be 38°.
Total angle in a triangle= 180
In that triangle
X+X+38= 180
The other angle is equal to X .
2X = 180-38
2X = 142
X =142/2
Answer: 30
Step-by-step explanation: square 24 and 18 (576 & 324) then add them together (900), then the square root of 900 is 30, so 30.
Marks
= 28/40
= 28/40 × 2.5/2.5
= 70/100
= 70%
Step 1 should be (14.4+18)...PEMDAS
