Question

Summative assignment 1 IX math anser the above questions

Answer 1

Here the answer for first question

The question is
4 root 3 root 2 square
By multiplying the exponents we get
$\sqrt[12]{ {2}^{2} } \: \:$
Then after we get
$( {2}^{2} ) \frac{1}{12}$
Then we get
$then \: we \: get \: 2 \: to \: the \: power \: of \: 1 \: by \: 6\:$

FINALLY THE ANSWER IS
$\frac{1}{32}$
Then coming to next question
$(30 - a) + (125 + 2a) = 180$
Here supplementary means 180
then we get
$30 - a + 125 + 2a = 180 \\ 155 + a = 180 \\ a = 180 - 155 \\ there \: fore .\: a = 25$
Then coming to last question
BASE = 12
AREA OF RIGHT ANGLED TRIANGLE IS = HALF BH
$\frac{1}{2} bh = 48 \\ \frac{1}{2 } \times 12 \times h = 48 \\ 6 \times h = 48 \\ h = \frac{48}{6 } \\ h = 8$
HOPE ALL THESE ANSWERS ARE HELPFUL
