Answer:
36° and 54°
Step-by-step explanation:
Complementary angles are angles whose sum equals to 90°
Hence C +D = 90°
The ratio of C &D = 2:3 respectively
Sum of the ratio = 2+3 = 5
Hence we divide each of the ratio by the sum of the entire ratio and then multiply by 90°
For angle C :
2/5 × 90
2×18 = 36°
For angle D :
3/5× 90
3×18 = 54°
Hence the angles are 36° and 54° respectively
To proof that we are actually right
C+D = 90°
36+54 = 90°
Hence the answer is right.
Answer:
10, and 4.
Step-by-step explanation:
39+48=87
87-13=74
74 divided by 7= 10 R4
Greatest amount of bricks= 10
Leftovers= 4.
Answer:
x = 10.5
Step-by-step explanation:
Intersecting chord theorem : If two chords intersect within a circle then the product of the measures of the segemnts made up of the chords are equal to each other.
For more reference to this, kindly view the attatched image.
Applying this theorem we would create an equation which would be 2 × x = 7 × 3
We then solve for x
2 × x = 7 × 3
==> simplify both sides
2x = 21
==> divide both sides by 2
x = 10.5
