ZA and ZB are complementary angles. If m_A= (7x + 28)° and m
snow_lady [41]

Answer:

mA=56 degrees

Step-by-step explanation:

Complementary angles adds up to 90 degrees. This imply that

(7x+28)+(8x+2)=90

From this equation, we can find x:

15x+30=90\\15x=90-30\\15x=60\\x=\frac{60}{15}\\x= 4

Now, we can substitute the value for x into the angle mA:

mA=(7*4+28)\\mA=(28+28)\\mA=56

Please answer this questions please. Will mark brainliest!!! The one with red circled.
patriot [66]

Answer/Step-by-step explanation:

1.a)(iv). \frac{1}{6} + (-\frac{7}{8}

Positive multiplied by negative = negative

\frac{1}{6} - \frac{7}{8}

\frac{4 - 21}{24} = \frac{-17}{24} = -\frac{17}{24}

2a.) 73.48 +(-37.3)

Note: + * - = -

73.48 - 37.3 = 36.18

3c.) 3\frac{3}{4} ÷ (-4\frac{2}{7})

Convert to proper fraction

\frac{15}{4} ÷ (-\frac{30}{7})

Change ÷ to × and flip the fraction on your right upside down

\frac{15}{4} * (-\frac{7}{30})

-\frac{15*7}{4*30}

-\frac{1*7}{4*2} = -\frac{7}{8}

3d.) -52.25 ÷ (-5.5) = \frac{-52.25}{-5.5}

(Note: - ÷ - = + )

\frac{-52.25}{-5.5} = 9.5

What is the correct answer to this
igomit [66]

Answer:

Perimeter = 9700 cm

Step-by-step explanation:

Dimensions of sides are;

12, 2x, 12, 5, 5, circumference of semi circle

Now, the semi circle has a radius of 7. Thus, the diameter = 7 × 2 = 14

We see that x is the diameter. Thus, x = 14

Thus; base of trapezium that is 2x = 2 × 14 = 28

Also, circumference of semi circle = 2πr = 2π × 7 = 44

Thus;

Perimeter of shape = 12 + 2(14) + 12 + 5 + 5 + 44

Perimeter = 97 m

Converting to cm, we multiply by 100 to get;

Perimeter = 97 × 100 cm

Perimeter = 9700 cm
