The answer to the item above would be the fourth choice, "none of the above". The measure of the angle formed by two intersecting perpendicular lines should be 90 degrees. The lines would form a section that is one-fourth of the Cartesian plane, thus, the 90 degrees.
4 × 3
−−−− = 6cm²
2
6 × 3 = 18cm²
10 × 5 = 50cm²
50 + 18 + 6 = 72cm²
Answer:
x = 10
y = 6
Step-by-step explanation:
<u>Vertical Angle Theorem</u>: When two straight lines intersect, the opposite vertical angles are always equal to each other.
⇒ m∠1 = m∠3 and m∠2 = m∠4
⇒ m∠1 = m∠3
⇒ 10x = 100
⇒ x = 10
<u>Linear pair:</u> Two adjacent angles which sum to 180°.
⇒ m∠1 + m∠2 = 180°
⇒ m∠3 + m∠4 = 180°
⇒ 100 + 10y + 20 = 180
⇒ 120 + 10y = 180
⇒ 10y = 60
⇒ y = 6
8x - 3 = -19
8x = - 19 + 3
8x = -16
x = -16/8
x = -2
answer: the number is negative 2
Answer:
h = 13 m
Step-by-step explanation:
The triangles are similar, so the ratios of corresponding sides are equal, that is
= = ( cross- multiply )
3h = 39 ( divide noth sides by 3 )
h = 13
