c
Step-by-step explanation:
I think since am still in secondary school
it's should be (x-4)(x-4)
120
You can find out how many she has graded by multiplying 150 by the decimal version of 20% (.20). Then, subtract the number you get by 150.
Hello!
∠E and the angle measuring 119 degrees (we'll refer to this as ∠A) can be classified as supplementary angles. Supplementary angles are two angles whose measures add to a sum of 180 degrees (a straight line). Therefore, we can conclude that sum of ∠E and ∠A is 180 degrees. We can use this information to create the following equation:
∠E + 119 = 180
Now subtract 119 from both sides of the equation:
∠E = 61
We have now proven that ∠E is equal to 61 degrees.
I hope this helps!
Answer:
The angles are 2x= 2x18°
=36° and 3x=3×18
=54°
Step-by-step explanation:
It is given that two complementary angles are in the ratio 2:3.
Consider 2x and 3x as the angles.
We know that, if two angles are complementary, then their sum is 90° .
Then, 2x+3x=90°
⟹ 5x=90°
⟹ x= 90/5
x=18°
Here, the angles will be 2x=2×18
°=36°
and 3x=3×18° =54 °
Hope this helps.
Greater=19
Smaller=3
Just use substitution
